Contacting HeadRoom

A Word About 

Your Hearing

People have a natural tendency to listen to music at much louder levels with 
headphones than they would with speakers. To avoid permanent hearing 
damage, it’s important to be careful not to listen at extremely loud levels (or 
to listen for too long at moderately loud levels). Because HeadRoom amps 
need to be able to drive even the most inefficient dynamic headphones to sat-
isfactory listening levels, they are also able to drive headphones of average 
or higher efficiencies to extremely high levels. As a result, even though the 
volume control on your HeadRoom amp may appear to be set to a low level, 
you may not be listening at a safe level. Generally speaking, when listening 
to headphones you should only turn up the volume to the point at which the 
sound isn’t too quiet.
As a general rule, sound pressure levels under 80 decibels will not damage 
hearing, even if experienced continually. On the other hand, anything over 
100 decibels may cause permanent damage very quickly. Sustained exposure 
to sound pressure levels anywhere in between can also be damaging —the 
louder the sound, the shorter the time required to cause permanent damage. 
Just to drive this message home, here’s a bit of information about hearing 
damage. The most common type of damage caused by prolonged or exces-
sively loud sound is called tinnitus. It manifests itself as a sustained buzzing 
and/or ringing in the ears, and can become a permanent condition. 
If you find that your ears are ringing or that there is a sensation of pressure or 
fatigue, your body is trying to tell you that your ears need a break. Give them 
a rest for a few days (or until they feel fresh). If you ignore these symptoms, 
you’re risking permanent hearing damage.
In addition, don’t fool yourself into thinking that you either have full-blown 
tinnitus or you don’t have it at all—there are different degrees of hearing dam-
age. For example, you might have a mild case where you only notice ringing 
in your ears in the quiet of your bedroom at night. However, once you have a 
slight case of tinnitus, your ears are much more susceptible to further dam-
age. So if you do experience mild symptoms, it’s important to be much more 
careful about your exposure to loud sounds.
Sorry to sound so sobering, but a lifetime of musical enjoyment requires ears 
in tiptop shape. Now that we’ve told you to be careful, don’t blame us if you 
blow it. If you have any more questions about hearing damage, call a doctor.
