Acoustics Issues for Schools

The importance of acoustics within educational spaces has recently been recognized by the American National Standards Institute. ANSI/ASA S12.60 sets the maximum limit of background sound levels within learning spaces at 35dBA, with maximum reverberation times of 0.6 to 0.7 seconds.

Room with no acoustic treatment

The Importance of Acoustics The understanding that poor acoustic environments within schools hinders learning and presents barriers for students with special needs is becoming more widespread. Within each school there are basic issues involving sound isolation and sound quality that should be addressed. Washington Administrative Code 246-366-110 limits exterior and interior noise within the school, and sound quality is equally important for classrooms, commons, gymnasiums, and music and auditorium spaces.

REVERBERATION TIME (RT60)

The reflective nature of a space will affect the sound quality within by creating long paths for sound to travel and by taking longer for sound to decay. These qualities will reduce the intelligibility of human voices and raise the overall noise level within a space. These qualities are quantified as reverberation time. Reverberation Time (RT60) within a space refers to the time it takes for sound to decay 60 decibels after its source was stopped. A high RT60 will contribute to the build-up of sound within a space; a lower RT60 will reduce noise and be ideal for spaces where understanding speech is essential. For each type of space there are acceptable levels based on room volume, as shown in the chart.

PERFORMING ARTS

Performing arts spaces have additional sound issues. It is important that the listener experience a "fullness" of sound within the space by creating accurate diffusion, using architectural elements that scatter sound.

Bethel High School Model Northwest Architectural Company

Performing Arts spaces should be completed so that listeners at every seat will experience the same sound levels, by frequency, from a performance. If the space is too absorptive, the result can be essentially "dead space" where sound is not scattered to the listeners. Modeling a space using EASE and CATT Acoustics allows for sound systems to be inserted and tested to evaluate specific speakers and speaker locations. Please see page 8 for more details on how we design performing arts spaces.

SOUND ISOLATION

Special attention to sound quality and isolation is necessary for numerous reasons within a school. Drama and music spaces require isolation from classrooms and hallways. Stages are valuable classroom spaces, and the commons is used for lunch. Mechanical equipment is often located in mezzanine spaces over corridors or in spaces adjacent to classrooms. These situations make it necessary to develop specific Floated Floor wall and floor/ceiling types for effective sound isolation, which must include details on ducting penetrations, light fixtures, and electrical junction boxes.

MECHANICAL NOISE

The evaluation of noise from HVAC (heating, ventilation, and air-conditioning) systems is applicable to classroom, library, auditorium, band, choral, drama, private office, and performing arts spaces. The American society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE) provides acceptable noise levels from HVAC systems as NC (Noise Criterion) curves. These are used as school district standards in Washington.

ENVIRONMENTAL NOISE

Under Washington Administrative Code 246-366-110 (Sound Control) and the State Board of Health Primary and Secondary School Regulations, noise from any source at the school site shall not exceed an hourly average (Leq) of 55 dBA or a maximum (Lmax) of 75 dBA during the time school is in session. Within the classroom, noise levels cannot exceed 45 dBA for a period of thirty seconds or more. An environmental noise control evaluation involves placing monitors at the site, and developing a source-pathreceiver model to predict interior noise levels. Recommendations are then provided, when necessary, to improve the windows and walls to achieve the design criteria.

Noise Descriptors When measuring noise that is fluctuating over time, a descriptor called equivalent A-weighted sound level, Leq is commonly used. The Leq contains the same amount of sound energy over a given time period as the measured fluctuating noise. It is the constant sound level in dB(A). The most common descriptors used to evaluate noise to residential buildings are: the Leq(h), the 24-hour Leq, and the Ldn. The Leq(h) is the average sound in dB(A) over a one hour period during day or night. The 24-hour Leq is the average sound in dB(A) over a 24 hour period, calculated using the hourly Leqs. The Ldn is the 24hour average with a 10 decibel penalty added to the hourly Leqs between 10 pm and 7 am. This 10 dB penalty represents the increased sensitivity during evening hours.

INNOVATIVE SOLUTIONS

We have worked to develop quiet heating, ventilation, and air-conditioning (HVAC) systems for classrooms that perform acoustically and reduce costs.

Using fully-perforated panels, ceilings can be assembled to have enough absorption to achieve the design criteria for classrooms, gymnasiums, and commons areas. Improvements to the standard perforated metal decks products have created new products that are more than three times more absorptive. We are proud of our commitment to using new ideas in order to solve problems. One of our most recent advancements on room acoustics involves developing solutions using a fully-perforated metal roof and deck system. Standard perforated decking systems, in most applications, do not provide sufficient absorption to be effective without the addition of wall and floor treatments. As a result, many projects have had materials added after construction to control reverberant noise. More cost-saving solutions are described in detail in our portfolio, beginning on page 13.

PERFORMING ARTS DESIGN

We use the most advanced modeling prediction methods to develop cost-effective solutions for performing arts spaces. This is done using EASE for sound system design, and CATT for Architectural Acoustics. We develop a 3-D model of sound propagation which we can use to evaluate characteristics of shaping, absorption, reflection, and diffusion in the room. 3-D ray tracing of ceiling and sidewall reflectors can be repeated while adjusting critical angles.

"The stage was full of students the seats packed with parents. The space functioned really well. Thanks for all your work to make this event successful. The building truly supports the energy of the users and the music programs! WOW................" Ron Harpel, AIA Architects Rasmussen and Triebelhorn

Using CATT for Architectural Acoustics We can develop a sound propagation model determining the most efficient use of materials and budget using CATT acoustics. It is a tool used to assist in the acoustic design of interior spaces, large or small. It allows us to optimize locations and volumes of materials for the best acoustic performance. The software is used to predict reverberation times and surface properties for all different materials. The data is first entered as a text file, called the geometry file, which includes dimensions for each wall and applies coordinates to each point. All coordinates can then be entered into a master file. From this, a 3-D stick model is created using CAD or CATT, and then we are able to make quick changes to materials and dimensions.

In the figure above, different views of the shaded 3-D model are shown. This is part of the designing phase of the model, in which different materials can be added to the corresponding coordinates. Sound systems can be inserted into the software and tested to evaluate types of speakers and speaker locations. When the model is finished, we can accurately predict sound contours, by frequency, for any location within the space for the entire audience. Changing materials within the model are accomplished and evaluated quickly. During construction, field measurements are performed to measure each aspect of acoustic performance.

Specifics of Designing with CATT Data for different sources, such as the human voice, can be adjusted for sound pressure levels. Receiver locations can be selected and sound played back to predict and make changes. In this manner, sound energy is distributed evenly, so all seats will have equally good responses. We also complete 3-D ray tracing to find acoustic blind spots or shadow zones. Using a shaded 3-D Model like the figure shown on the following page in the final stage of design, different procedures such as ray tracing, contours, and source directivity can be visualized.

CATT software has the ability to import files from AutoCAD. This allows the user to take existing drawings as a foundation from which to build.

Properties such as absorption, reflection, and diffusion coefficients can be entered and modified, and we can predict how the space will perform, with or without an audience. Diffusion elements are used to scatter sound by frequency. With CATT being able to add diffusive elements into the model we are able to create custom wall systems, or use offthe-shelf products; a library of different materials can put into the model. In the prediction module, various environmental conditions which can affect the results, including relative humidity, temperature, background, and mechanical noise, can be adjusted to predict the finished environment.

ENVIRONMENTAL NOISE EVALUATIONS

Collecting sound data and predicting noise levels is only part of the solution. The most important part is developing mitigation recommendations that are practical and achieve the design requirements.

Collecting Data Evaluations are completed by stationing monitors at critical site locations where traffic from cars, buses, and planes can best be evaluated for their impact to the site. These monitors are typically hidden and secured to a tree or building and left for a period of 2 to 4 days. Data collected by monitors include the average noise level for each hour and for a 24-hour period. In addition, events that exceed programmed limits are documented for the duration, time-of-day, sound level, and highest sound level.

Application The colleted data can then be used in programming models to predict noise levels exterior and interior environments. We are currently using Environmental Noise Model (ENM) and Stamina software to evaluate and predict noise levels. Once the noise levels are predicted, we develop mitigation recommendations that are practical and achieve the design requirements. Typically these recommendations involve glazing in windows and curtain wall assemblies. In areas concerning aircraft over flight our recommendations contain information for roof assemblies, walls, windows and doors. We have recently completed projects near railroad tracks, highways, and airports achieving all design requirements.

HVAC NOISE AND VIBRATION CONTROL

Vibration from rooftop equipment can generate noise through the structure that can be louder than the noise radiated from the fan. During construction we complete a detailed inspection of noise control elements on HVAC equipment.

Evaluation and Application We evaluate supply, intake, and radiated noise of HVAC units from the location of the equipment. Predictions based on ducting and air distribution elements provide a starting point for recommendations to achieve the Noise Criteria for specific spaces. Recommendations typically include duct liner, silencers, plenums, equipment location and ducting layout. We provide drawing notes that are supported by CAD details and specifications. We commonly find issues with radiated noise and vibration from rooftop and mezzanine mechanical equipment located near classrooms or sensitive areas. The use of VAV boxes and terminal units above classrooms is one method we have been successful using modest mitigation measures to achieve acceptable noise levels. Normally, these changes have minimal impact on the system cost.

Shaping an Ideal Theater

Bethel High School

Northwest Architecture Company Guy Overman, Project Manager 206-441-4522 Construction Start 2004

Challenges This school presented us with a great opportunity to design a theatre which would satisfy requirements for music and speech. In order to create the ideal acoustical environment, we had to make changes to the shape of the space in the original drawings. This difficult process was accomplished by the design team in the interest of creating the best acoustics possible. This project was ideal because working with the best room shaping allows time to concentrate on the small details rather than focusing on fixing problem areas. Solutions The auditorium was modeled using EASE software to develop the ideal amount of absorption, reflection, and diffusion elements. Specific acoustical treatments for the theater include a system of suspended clouds, which enhance the direct sound by providing useful early reflections from the stage towards the audience. These treatments are designed from standard materials to be cost-effective. Additional Involvement We completed detailed evaluations to control mechanical noise and vibration and reverberant sound within the gym, library, and classrooms. A resilient hung ceiling was designed in the industrial education classrooms to prevent sound transmission to the above rooms. Detailed recommendations to isolate spaces from noiseproducing areas including band and coral areas, gym, offices, corridors, and commons were developed.

We worked closely and effectively with the teams at NAC and Bethel School District in designing acoustical recommendations for this uniquely laid-out school. The 168,ooo sq ft building contains three `houses', each with teachers offices, conference areas, and a center commons space. The building also contains a 400-seat auditorium and a 2,000-seat main gymnasium.

Acoustics and Aesthetics

University of Washington Conibear Shellhouse

The Miller/Hull Partnership, LLP Katie Popolow, AIA, Project Manager 206-682-6837 Construction Start 2004

Scope: All aspects of acoustical design in the renovation of the existing shellhouse, including the addition of a dining hall, classrooms, team training rooms, a computer learning center, and an office space. Challenges: When completed in 2004, this building will be durable enough in design to stand up to everyday uses by the students, but attractive enough to be used for key campus events. We needed to meet the design standards of Miller/Hull, an AIA 2002 National Award Winner, while working within the budget. Solutions: We worked closely with Miller/Hull throughout the design phase to ensure the Northwest aesthetic design would not be sacrificed for acoustics needs. We narrowed our search for the right materials based on the design, and tailored our recommendations to the materials selected by Miller/Hull. Specifics of design include sound isolation in the floor/ceiling assembly from the practice rooms to the classrooms, both noise control and room acoustics for the dual-use cafeteria, speech intelligibility in the classroom, lecture hall, and computer study spaces, and sound vibration and isolation for the rooftop mechanical equipment. The dining hall was designed with an alternating metal and wood ceiling to achieve both aesthetic and acoustic ideals. Comments: Project Manager Katie Popolow, AIA, enjoyed working with Bill and Anita on the project and appreciated their "pleasing personalities, proactive work, and interest in finding low-cost solutions".

Solutions for Sustainable Schools

The Bush School Addition & Renovation

The Miller/Hull Partnership, LLP Steve Southerland, AIA 206.682.6837 Construction Start 2004

Scope We provided all aspects of acoustical design for the addition of a new K-12 building and library, as well as upgrading the existing gym. The Bush School was designed to LEED criteria, and uses a natural ventilation system. Challenges The use of chimneys, fans, and operable windows in a sustainable school create additional acoustic challenges for environmental noise control and interior room acoustics. Chimneys containing exhaust assist systems run through classrooms create noise. Noise due to the necessity of keeping windows open as well as from mechanical equipment to neighboring houses was a big concern for this project. Solutions In accordance with Leadership in Energy and Environmental Design guidelines and Washington Administrative Code, our design recommendations had to meet a Noise Criteria 35 within classrooms. We needed to improve upon the existing design of vertical unit ventilators by working to reduce noise levels. We worked with three manufacturers to improve their products. We were able to improve these units and design a mechanical system which adheres to code requirements and LEED guidelines. The Bush School was founded in 1924 and is Seattle's oldest independent K-12 school. This school is spread over nine acres in the Madison Valley Neighborhood. We took special care in designing recommendations in order to ensure that neighboring communities would not be exposed to noise from rooftop mechanical equipment and interior sources.

State-of-the-Art Space Modeling

Arlington High School and PAC

McGranahan Architects Chris Lilley, AIA, Principal 253.383.3084 Completed in 2004

Scope Acoustical design recommendations were designed to cover all aspects of the new Arlington High School and Performing Arts Center. The proposed building is a comprehensive facility covering 52 acres, designed to house 1,600 students, with core spaces sized to allow the school to be enlarged to accommodate 2,000 students. Challenges Developing a performing arts auditorium for the community of Arlington which would satisfy requirements for drama, orchestra, choral, and band performances. Solutions The performing arts auditorium was modeled using EASE to develop absorption, reflection, and diffusion characteristics for the space. These elements, which were carefully developed to be durable and longlasting, were incorporated into the space plans. Highlights off the 700-seat-theater include an orchestra pit, a large stage area, modified fly loft, direct access to the fine arts wing of the new school, and state of the art sound and lighting systems. Additional Involvement Interior absorptive treatments were specified in the band, coral, gym, library, halls, and commons. Particular attention was made to control mechanical noise from mezzanine units. Recommendations include extensive use of perforated ceiling and wall treatments to control reverberant noise.

Innovative Environmental Noise Solutions

Pioneer Elementary School

Hutteball & Oremus Architects Bill Chaput, Project Manager: 425-828-8948 Completed September 2002 Scope: Controlling environmental noise

and designing elements for architectural and engineering acoustics, including noise transmission from music and mechanical spaces to more sensitive learning spaces. Challenges: The school is located along SR 9 in Arlington. While this location provides excellent community access, there is significant noise from the highway along the eastern property line. We needed to develop a cost-effective solution to prevent excessive noise while allowing traffic to move in and out of the facility. Solutions: An environmental noise assessment was completed to determine the impact that noise from the highway would have on the new school. Environmental noise monitors and ENM software were used to document noise levels and determine sound propagation. We designed a berm/barrier wall with an opening for traffic to reduce noise from the highway. To reduce costs, the berm was built using existing dirt rather than importing it to the site. Our recommendations included the berm, barrier, path, and plants and were incorporated with the landscape architect in the final design. Additional Work: Architectural and engineering acoustic design recommendations were also provided. Sound quality in the commons was evaluated for music and drama. Classrooms were designed to achieve a NC35. The library, gym, and the music room were designed with the proper room absorption, reflection, and diffusion.
