Architectural Acoustics Topics
- Acoustic Barriers
- An acoustic barrier between two rooms.
- Acoustic Cavity
- The acoustics of enclosed volumes are important when considering sound propagation within the volume.
- Acoustic Ducts
- Ducts with an acoustic treatment or shaped to reduce or control acoustic wave propagation.
- Acoustic Filter Elements
- There are a number of different types of acoustic filter elements that are used in many different applications.
- Acoustic Material
- Any material considered in terms of its acoustical properties.
- Acoustic Pack
- Name given to all of the soft absorptive parts used to reduce noise in a vehicle.
- Acoustic Source Location
- There are a number of different ways by which the location of a noise source may be found.
- Acoustic Sources
- The simplest acoustic source is the monopole.
- Acoustic Tile
- A descriptive term often used to describe commercially available room acoustic treatment.
- Acoustic Wedges
- The acoustic treatment used on all surfaces of an anechoic chamber.
- Acoustics
- From the Greek akouein ( "to hear") a term sometimes used for the science of sound in general.
- Architect
- A person who designs all kinds of structures.

- Artificial Reverberation
- Reverberation generated by electrical or acoustical means to simulate that of concert halls, etc.
- Average Room Absorption Coefficient
- Total room absorption in sabins or metric sabins, divided by total room surface area in consistent units of square feet or square metres.
- A Weighting
- This is the most generally used filter when making overall noise measurements.
- Cavity Acoustics
- The acoustics associated with enclosed volumes.
- Dead Room
- Room characterized by a relatively large amount of sound absorption and a relatively short reverberation time.
- Decibel
- The human ear responds logarithmically and it is convenient to deal in logarithmic units in audio systems.
- Duct Acoustics
- Ducts with acoustic waves propagating through them exist in many forms.
- Field Sound Transmission Class
- The same as STC rating except as measured in the field in accordance with standard methods.
- Flanking Sound Transmission
- The transmission of sound from the sound source room to the receiving room by paths other than through the partition under test.
- Hard Room
- A room in which the surfaces have very low values of sound absorption and are therefore highly reflective.
- LAE
- Abbreviation for sound exposure level.
- Reverberation Room
- Room having a long reverberation time, specially designed to make the sound field therein as diffuse as possible.
- Reverberation Time
- The time in seconds required for sound pressure at a specific frequency to decay 60 dB after a sound source is stopped.
- Room Absorption
- Sum of Sabine absorption due to objects and surfaces in a room, and due to dissipation of energy in the medium within the room.
- Room Acoustics
- The general acoustic requirements of a room depend on the use.
- Room Modes
- Frequencies at which sound waves in a room resonate (in the form of standing waves), based on the room dimensions.
- Soft Room
- Room with highly sound absorptive surfaces.
- Sound Transmission Class
- In acoustics, a single number rating for describing sound transmission loss of a wall or partition.
- Sound Transmission Coefficient
- Of a partition, in a specified frequency band, the fraction of the airborne sound power incident on the partition that is transmitted by the partition and radiated on the other side.
- Sound Transmission Loss
- Of a partition, in a specified frequency band, ten times the common logarithm of the ratio of the airborne sound power incident on the partition to the sound power transmitted by the partition and radiated on the other side.
- Source Room
- In architectural acoustical measurements, the room that contains the noise source or sources.
- Structural Acoustic Coupling
- The physics relating to the vibration of a panel and the sound radiated from it or the acoustic excitation excitation of the panel.
