The branch of physics that deals with the production, control, transmission, reception, and effects of sound

• Acoustics

• Airborne sound

• Soundproof

Sound radiated directly into and transmitted through the air

• Acoustics

• Airborne sound

• Soundproof

Impervious to audible sound

• Acoustics

• Airborne sound

• Soundproof

The intensification and prolongation of sound produced by sympathetic vibration

• Resonance

• Sympathetic vibration

• Direct sound

• Attenuation

A vibration induced in one body by the vibrations of exactly the same period in a neighboring body

• Resonance

• Sympathetic vibration

• Direct sound

• Attenuation

Airborne sound traveling directly from a source to the listener

• Resonance

• Sympathetic vibration

• Direct sound

• Attenuation

A decrease in energy or pressure per unit area of a sound wave, occurring as the distance from the source increases as a result of absorption, scattering, or spreading in three dimensions

• Resonance

• Sympathetic vibration

• Direct sound

• Attenuation

The time in seconds required for a sound made in an enclosed space to diminish by 60 decibels

• Reverberation time

• Reverberation

• Decay rate

• Focusing

The persistence of a sound within an enclosed space, caused by multiple reflections of the sound after its source has stopped

• Reverberation time

• Reverberation

• Decay rate

• Focusing

The rate of decrease of sound pressure level after its source has stopped, usually expressed in decibels per second

• Reverberation time

• Reverberation

• Decay rate

• Focusing
