How it works
Q. How does ultimate ear protection
safeguard hearing?
Apart from being uncomfortable and tiring,
high noise levels can permanently damage hearing. Ultimate
manufacture custom made hearing protection that could
be used by any one to safeguard their hearing. Research
resulted in a special earpiece that cut out no more sound
than was necessary to ensure the right amount of protection,
constructed from a soft durable medical grade silicone.
The concept of any custom made item is its
individuality and uniqueness to its user.
ultimate ear defenders are manufactured
in such a way that they fit comfortably, within the confines
of an individuals ear, each pair being individually crafted
under the strictest conditions from exact impressions
of the users' ears. The durability of our product will
provide years of use (most users replace after five years)
which equates to about four pence per day - a small price
to pay to guarantee the protection of your most important
senses?
Q. How much noise can a person tolerate?
The strength of a sound is determined by
the pressure of the sound waves and is expressed in decibels:
dB(A). dB(A) measurements are corrected to the sensitivity
of the human ear. The quietest audible sound is 0dB(A).
The threshold of pain begins at 120 dB(A).
Sound pressure
Each
time the sound level is increased by 3 dB, the intensity
of that sound is doubled (i.e., it is twice as loud).
Each time you double the sound intensity, the safe listening
time is halved. The louder the sound, the sooner the chance
of permanent hearing damage.
