MODULE-1 – BUILDING ACOUSTICS
(COMMON ACOUSTICAL DEFECTS AND
RECOMMENDED REMEDIES) Presented by Ar. Manish Kumar, Assistant Professor in
Architecture Department at Axis Institute of
Architecture
The document describes a primary school building project in Kigali, Rwanda. It discusses the climate context, design of the school which includes seven building houses and nine classrooms arranged on platforms to adapt to the sloping site. Classrooms are simply rectangular with flexible furniture arrangements. An administration/library building is also included. Construction materials used stabilized earth bricks, thatched doors and reed ceilings. Natural lighting penetrates through brick hollows and ceilings. Ventilation was challenging due to site topography.
1. Building acoustics involves controlling noise transmission between spaces and noise levels within spaces. Noise can reduce comfort and efficiency if it is troublesome.
2. The best way to address noise problems is to take proper acoustic precautions in the design and construction of a building. This ensures each space has the correct acoustic climate and noise transmission levels are compatible with usage.
3. Sources of indoor noise include activities like cooking, footsteps, doors slamming, furniture moving, plumbing, and appliances. Outdoor noise sources are traffic, construction, and landscaping activities.

A NEW CONCEPT IN SCHOOL PLANNING IS THE USE OF A LARGE TEACHING AREA WITH
SIMULTANEOUS INSTRUCTIONS IMPARTED TO SEVERAL GROUPS OF STUDENTS.
THE SHAPE OF SUCH SPACES MAYBE AS LINEAR AS POSSIBLE WITH A WIDTH TO HEIGHT
RATIO OF 5:1 OR GREATER.
JUDICIOUS POSITIONING OF PARTIAL HEIGHT BARRIERS 1.8 M TO 2.1 M IN HEIGHT CAN
IMPROVE THE SOUND ATTENUATION BETWEEN TEACHING GROUPS
MIN. SOUND REDUCTION BETWEEN ROOMS IN
DIFFERENT CL ASSES
MINIMUM SOUND REDUCTION BETWEEN ROOMS IN THE DIFFERENT CLASS IS 45 DB
SUBJECTED TO FOLLOWING NORMS :-
A) IN SCHOOLS WHERE NOISY ACTIVITY SUCH AS SHEET METAL WORK, PLUMBING
AND WOODWORK ARE LIKELY TO BE PRACTICISED EXTENSIVELY IN NORMAL
HOURS REGARDED AS SPECIAL CATEGORY AND MORE THAN 45 DB ISOLATION IS
REQUIRED

9. RECOMMENDATIONS…..
WOODEN FURNITURE SHOULD BE
PROVIDED.
RUBBER BUFFERS SHOULD BE PROVIDED
TO THE LEGS OF THE FURNITURE.
FURNITURE SHOULD BE FIXED IN
PRIMARY SCHOOLS.
NOISE REDUCTION WITHIN STUDY SPACES…..
SOUND ABSORBENT MATERIALS PLAY A USEFUL PART IN REDUCING THE BUILT-UP OR
AIR-BORNE NOISE AT SOURCE.
IN ROOMS, LIKE CLASSROOMS, ASSEMBLY HALLS AND MUSIC ROOMS, SHORT
REVERBERATION TIME UNDER OCCUPIED CONDITIONS IS REQUIRED.
TYPICAL CLASSROOMS AND MEETING ROOMS SHOULD HAVE A LAY-IN ACOUSTIC TILES.

10. NOISE REDUCTION WITHIN
STUDY SPACES…..
THE MAXIMUM REVERBERATION TIMES PERMISSIBLE FOR THIS PURPOSE ARE USUALLY
SHORT TO GIVE ADEQUATE NOISE CONTROL BUT IN ADDITION, THE REVERBERATION
TIME SHOULD NOT BE EXCESSIVE UNDER EMPTY CONDITIONS, BECAUSE NOISE MAY
OCCUR IN THESE ROOMS WITH VERY FEW OCCUPANTS.
IN ROOMS, LIKE CLASSROOMS, ASSEMBLY HALLS AND MUSIC ROOMS, SHORT
REVERBERATION TIME UNDER OCCUPIED CONDITIONS IS REQUIRED.
TYPICAL CLASSROOMS AND MEETING ROOMS SHOULD HAVE A LAY-IN ACOUSTIC TILES.
WALLS TYPICALLY SHOULD BE A HARD, SOUND-REFLECTIVE MATERIAL, SUCH AS
GYPSUM BOARD OR MASONRY, SHAPING AND DIFFUSION ON WALLS IN LARGER ROOMS
SHOULD BE CONSIDERED TO IMPROVE SPEECH REFLECTION PATTERNS AND ELIMINATE
FLUTTER ECHOES.
THE WINDOWS SHOULD BE SPECIFIED AS AN INSULATING ASSEMBLY WITH DIFFERENT
PANE THICKNESSES TO REDUCE OUTSIDE NOISE

11. WORKSHOPS REQUIRE MORE THAN
45DB INSULATION FROM ROOMS OF ANY
OTHER CLASS.
IN SCHOOLS FOR DEAF. DEAF CHILDREN ARE TAUGHT BY MEANS OF HEARING AIDS,
WHICH CANNOT BE USED SATISFACTORILY IN HIGH NOISE LEVELS OR IN REVERBERANT
CONDITIONS.
CORRIDOR WALLS FROM CLASSROOMS, LABORATORIES, AND MEETING ROOMS SHOULD
BE A MINIMUM OF A SINGLE LAYER OF (1.6 CM) GYPSUM BOARD ON EACH SIDE OF A
METAL STUD.
DOORS SHOULD TYPICALLY NOT BE LOCATED BETWEEN TWO CLASSROOMS OR OTHER
SOUND-CRITICAL SPACES
CONSTRUCTION OF SOLID-CORE WOOD OR HOLLOW METAL WITH APPLIED ACOUSTICAL
DOOR SEALS AND SWEEPS TO CONTROL SOUND LEAKAGE AROUND THE PERIMETER OF
THE DOORS.
ASSEMBLY HALLS AND MUSIC ROOMS REQUIRE 45DB INSULATION FROM THE ROOMS IF
THE LATTER ARE VERY NOISY

14. SPECIFY CEILING, WALLS AND FLOOR TREATMENT TO MEET THE REVERBERATION
CONTROL REQUIREMENTS OF STANDARD.
SPECIFY SOUND INSULATING WINDOWS TO BLOCK STREET AND ENVIRONMENTAL
NOISES.
LIMIT OR OMIT OPEN SPACE CLASSROOMS IN THE SCHOOL.
FOR GENERAL CLASSROOMS WITH NO FIXED LECTURE POSITION AND CEILING LESS
THAN 3MT, PLACE MAXIMUM ABSORBING MATERIAL ON CEILING. OVER 3MT AN
INCREASING AMOUNT SHALL BE ON WALLS.
FOR CLASSROOMS WITH FIXED OR PREDOMINANT TEACHER POSITION, DON'T PLACE
SOUND ABSORBING MATERIALS JUST ABOVE AND IN FRONT OF TEACHER.
IN LECTURE HALLS, USE SOUND REFLECTING MATERIAL OVER THE LECTERN, SOUND
ABSORBING UPHOLSTERED CHAIRS AND BACK WALL SOUND ABSORBING.
CORRIDORS SHOULD GENERALLY HAVE TOTAL SURFACE AREA OF SOUND ABSORBING
MATERIALS ON THE CEILING & WALLS NOT LESS THAN 50%OF FLOOR AREA AND UPTO
75% OVERALL(FOR HIGH TRAFFIC).
USE WALL MOUNTED OR PENDENT LIGHT FIXTURES RATHER THEN CEILING TO PROVIDE
MAXIMUM CEILING AREA FOR ACOUSTIC TREATMENT.
STAGGER ROOM ENTRANCES ALONG CORRIDORS TO REDUCE DIRECT SOUND
TRANSMISSION THROUGH OPEN DOORS.
CARPETING CAN BE HELPFUL FOR RESISTING CHAIR AND FOOT SOUND.
