Safe listening levels?
We often get asked by people “what is the maximum SPL that can be produced by your loudspeakers?“. One point these people always miss is that in most cases, our speakers can be driven by enough power to push your ears in to the danger zone. Therefore I felt it necessary to post the following information to help you understand the fact you might be damaging your hearing at certain listen levels.
Decibel Exposure Time Guidelines
Accepted standards for recommended permissible exposure time for continuous time weighted average noise, according to NIOSH and CDC circa 2002. For every 3dB’s over 85dB, the permissible exposure time before possible damage can occur is cut in half.
85dB = 8 hours
88dB = 4 hours
91dB = 2 hours
94dB = 1 hour
97dB = 30 minutes
100dB = 15 minutes
103dB = 7.5 minutes
106dB = 3.75 minutes
109dB = 1.875 minutes
112dB = 0.9375 minutes
115dB = 0.46875 minutes
As an example, if you used the K3 floor-standing loudspeaker and an amplifier capable of producing 200W into 4 Ohms. Driven at full volume as a stereo pair in a room, you would be producing 116dB @ 1m.
