Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of
sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard
against this by setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level:
a. Start your volume control at a low setting.
b. Slowly increase the sound until you can hear it comfortably and clearly, and without
distortion. Once you have established a comfortable sound level, leave it there.
