Architectural acoustics (also known as room acoustics and building acoustics ) is the science and technique for achieving good sound within the building and is a branch of acoustic technique. The first application of modern scientific methods for architectural acoustics was done by Wallace Sabine in the Fogg Museum's lecture hall which then applied his new knowledge found on the design of Symphony Hall, Boston.
Architectural acoustics can include clarity of good speech in theater, restaurant or railway station, improving the quality of music in concert halls or recording studios, or suppressing noise to make the office and home a more productive and enjoyable place to work and live in. Architectural acoustic design is usually performed by acoustic consultants.

Build skin envelope
This science analyzes the transmission of sound from building the exterior envelope to the interior and vice versa. The main noise lines are roofs, roofs, walls, windows, doors and penetrations. Adequate controls ensure room functionality and are often required based on local building codes and city codes. An example would be to provide a suitable design for a house to be built close to a high-volume road, or under a flight path from the main airport, or from the airport itself.

Control inter-space noise
Science limits and/or controls the transmission of sound from one building space to another to ensure spatial function and privacy of speech. Typical sound tracks are ceilings, partitions of the room, acoustic ceiling panels (such as ceiling panels dropped from wood), doors, windows, flanking, ducting and other penetrations. The technical solution depends on the noise source and the acoustic transmission line, eg noise by step or sound by the vibration of the airflow (water). An example would be to provide an appropriate party wall design in the apartment complex to minimize reciprocal interference due to noise by residents in adjacent apartments.
Acoustic interior space
It is the science of controlling the surface of a room based on the nature of absorbing and reflecting sound. Excessive buzzing time, which can be calculated, can cause poor speech clarity.
Sound reflection creates a standing wave that produces a natural resonance that can be heard as a pleasant or irritating sensation. The reflective surface can be tilted and coordinated to provide good sound coverage for the audience in the concert hall or the recital music room. To illustrate this concept, consider the difference between a modern large office meeting room or traditional classrooms and classrooms with all hard surfaces.
Surface interior building can be constructed from various materials and finishing touches. The ideal acoustic panel is a faceless panel or an end material that interferes with an acoustic substrate or substrate. Cloth-coated panels are one way to improve acoustic absorption. The hollow metal also shows the quality of the sound absorber. The end material is used to cover the acoustic substrates. Mineral fiber board, or Micore, is a commonly used acoustic substrate. The end material often consists of cloth, wood or acoustic tiles. Fabrics can be wrapped around the substrate to create what are called "pre-fabricated panels" and often provide good sound absorption when placed on the wall.
Prefabricated panels are limited to substrate sizes ranging from 2 to 4 feet (0.61 m² - 1.22 m) up to 4 times 10 feet (1.2 m m 3.0 m). Fabrics stored in wall-mounted perimeter systems, referred to as "acoustic wall panels in place". It is built by framing the perimeter path into shape, filling the acoustic substrate and then stretching and tucking the fabric into the perimeter frame system. Wall panels in place can be built to accommodate door frames, pedestals, or other intrusions. Large panels (generally larger than 50 square feet (4.6 m 2 )) can be made on walls and ceilings with this method. Wooden ends can consist of slots or holes routed and give a natural look to the interior space, although acoustic absorption may not be good.
There are three ways to improve acoustics at work and solve workplace noise problems - ABC.
- A = Absorb (through drapes, rugs, ceiling tiles, etc.)
- B = Block (via panel, wall, floor, ceiling, and layout)
- C = Close-close (via voice cap)
Mechanical equipment sound
Building a service noise control is a science of controlling the noise generated by:
- ACMV system (air conditioner and mechanical ventilation) in the building, called HVAC in North America
- Elevator
- The power generator is positioned inside or attached to the building
- Any building service infrastructure component that emits sound.
Inadequate control may cause a high level of sound in a room that can interfere with and decrease the clarity of sound. A typical improvement is the mechanical vibration isolation equipment, and sound traps in need of ducts. Sound cover can also be made by adjusting the HVAC noise to a predetermined level.
