Architectural acoustics is the science of controlling sound within buildings. The first application of architectural acoustics was in the design of opera houses and than concert halls. More widely, noise suppression is critical in the design of multi-unit dwellings and business premises that generate significant noise, including music venues like bars. The more mundane design of workplaces has implications for noise health effects. Image File history File links Please see the file description page for further information. ...

Building skin envelope
This science analyzes noise transmission from building exterior envelope to interior and vice versa. The main noise paths are roofs, eaves, walls, windows, door and penetrations. Sufficient control ensures space functionality and is often required based on building use and local municipal codes. An example would be providing a suitable design for a home which is to be constructed close to a high volume roadway, or under the flight path of a major airport, or of the airport itself. A roof is the top covering of a building that prevents the ingress of weather into the building interior. ...

The term penetration can mean several things: In business, penetration is often short for market penetration, the degree to which a product or service is known and/or used among potential customers. ...
Inter-space noise control The science of limiting and/or controlling noise transmission from one building space to another to ensure space functionality and speech privacy. The typical sound paths are room partitions, ceiling panels, doors, windows, flanking, ducting and other penetrations. An example would be providing suitable party wall design in an apartment complex to minimise the mutual disturbance due to noise by residents in adjacent apartments.

Interior space acoustics This is the science of controlling a room's surfaces based on sound absorbing and reflecting properties. Excessive reverberation time can lead to poor speech intelligibility, which can be calculated [1]. Reflective surfaces can be angled and coordinated to provide good coverage of sound for a listener in a concert hall or music recital space. To illustrate this concept consider the difference between a modern large office meeting room or lecture theater with a traditional classroom with all hard surfaces.

Interior building surfaces can be constructed of many different materials and finishes. Ideal acoustical panels are those without a face or finish material that interferes with the acoustical infill or substrate. Fabric covered panels are one way to heighten acoustical absorption. Finish material is used to cover over the acoustical substrate. Mineral fiber board, or Micore, is a commonly used acoustical substrate. Finish materials often consist of fabric, wood or acoustical tile. Fabric can be wrapped around substrates to create what is referred to as a "pre-fabricated panel" and often provides the good noise absorption if laid onto a wall. Prefabricated panels are limited to the size of the substrate ranging from 2'x 4' to 4' x 10'. Fabric retained in a wall-mounted perimeter track system, is referred to as "on-site acoustical wall panels" This is constructed by framing the perimeter track into shape, infilling the acoustical substrate and then stretching and tucking the fabric into the perimeter frame system. On-site wall panels can be constructed to accommodate door frames, baseboard, or any other intrusion. Large panels (generally, greater than 50 square feet) can be created on walls and ceilings with this method. Wood finishes can consist of punched or routed slots and provide a natural look to the interior space, although acoustical absorption may not be great.

There are three ways to improve workplace acoustics and solve workplace sound problems – the ABC’s.
A = Absorb (usually via ceiling tile)
B = Block (via workstation panels, wall placement and workspace layout)
C = Cover-up (via electronic sound masking)
While all three of these are recommended to achieve optimal results, C = Cover-up by increasing background sound produces the most dramatic improvement in speech privacy –– with the least disruption and typically the lowest cost.
Mechanical equipment noise Building services noise control is the science of controlling noise produced by: - ACMV (air conditioning and mechanical ventilation) systems in buildings, termed HVAC in the USA
- Elevators
- Electrical generators positioned within or attached to a building
- Any other building service infrastructure component that emits sound.
Inadequate control may lead to elevated sound levels within the space which can be annoying and reduce speech intelligibility. Typical improvements are vibration isolation of mechanical equipment, and sound traps in ductwork. Sound masking can also be created by adjusting HVAC noise to a predetermined level. All-air and air-water HVAC systems use air ducts, outlets, and inlets installed throughout their buildings. ...
