What Are Room Acoustics?

Acoustic Fundamentals

Room acoustics is the science of how sound behaves in enclosed spaces — how it travels, reflects, absorbs, and diffuses.

Sound Wave Propagation: Pressure Level

Sound Pressure Level (SPL) measures sound intensity in decibels (dB). Different spaces require different pressure levels depending on their use.

Sound Wave Propagation: Frequency

Frequency determines the pitch of sound — low frequencies (bass) behave differently than high frequencies. Each acoustic material handles a specific frequency range.

Reverberation Time

Reverberation Time (RT60) is the time it takes for sound to decay by 60 decibels after the source stops. Different rooms require different reverberation times.

Echo

Echo is a distinct sound reflection that occurs when a sound wave reflects off a distant surface and returns with a noticeable delay.

Sound Absorption

Sound-absorbing materials convert acoustic energy into minimal heat, reducing reflections and improving sound quality in the space.
