= 84.8 dB
Room acoustics and acoustic properties, decibel A, B and C, Noise Rating (NR) curves, sound transmission, sound pressure, sound intensity and sound attenuation.
Noise is usually defined as unwanted sound - noise, noise generation, silencers and attenuation in HVAC systems.
Maximum recommended sound pressure levels in rooms like kindergartens, auditoriums, libraries, cinemas and more.
Barriers and enclosures to reduce noise sound pressure levels from machines.
The attenuation in a room depends on the location of the sound source and the receiver - and the room constant.
The sound reverberation time indicates how long it takes until the sound pressure level in a room is decreased with 60 dB.
Mean absorption coefficients and reverberation times in typical rooms.
Room sound absorption and absorption coefficients for common materials like plaster walls, brickwork, plywood panels and more.
Room size, absorption characteristics - and attenuation in direct sound fields.
Acoustic power of sound per unit area.
Sound Pressure is the force of sound on a surface perpendicular to the propagation of sound.
