WORKING SAFELY WITH SOUND
Although your new console will not make any noise until you feed it signals, it has the capability to pro-
duce sounds which when monitored through a PA system or headphones can damage hearing over time.
The table below is taken from the Occupational Safety & Health Administration directive on Occupational
noise exposure (1926.52):
PERMISSABLE NOISE EXPOSURE
DURATION PER DAY, HOURS
SOUND LEVEL dBA SLOW RESPONSE
8 90
6 92
4 95
3 97
2 100
1.5 102
1 105
0.5 110
<0.25 115
Conforming to this directive will minimise the risk of hearing damage caused by long listening periods. A
simple rule to follow is the longer you listen the lower the average volume should be.
Please take care when working with your audio - if you are manipulating controls which you don’t under-
stand (which we all do when we are learning), make sure your monitors are turned down. Remember that
your ears are the most important tool of your trade, look after them, and they will look after you.
Most importantly - don’t be afraid to experiment to find out how each parameter affects the sound - this
will extend your creativity and help you to get the best results.
Recommended headphone impedance is 50-600 ohms.
