What is Tinnitus?
Tinnitus is the term for the perception of sound in one or both ears when there is no external sound, often referred to as ringing in the ears.
The "ringing" can be a soft background noise, or an overpowering noise that drowns out all other sounds, and can be ocassional or constant. The false data may be translated as a range of sounds, from ringing to whistling to buzzing, pulsing, hissing, clicking, or chirping, and usually accompanies hearing loss.
What is a Decibel?
dec·i·bel: a unit used to express the intensity of a sound wave. Abbr. dB
What is NRR?
The strength of hearing protection is given in its noise reduction rating (NRR).
The NRR indicates the average number of decibels sound will drop when inserted into your ear. The actual number that decibels will drop varies greatly depending on the pitch (the highness or lowness of sound), and volume.
What is a Noise Braker?
The Noise Braker is hearing protection utilizing the Hocks Noise Filter®. The filter, inserted into hearing protection, allows air and sound to enter the ear, while protecting the wearer's hearing.
The Hocks Noise Filter® is designed to reduce the intensity of sound waves as the sound waves get stronger. Hearing protection utilizing the Hocks Noise Filter® allows the wearer to carry on a normal conversation. The normal voice can be heard with a slight reduction of volume, while the background noise is filtered out to a greater extent.
