Electronic Hearing Protection : What is it?

Electronic Hearing Protections

Electronic hearing protection are protective devices used for dampening low-frequency sounds and loud noises. They come in ear muff and hearing-aid-like structures worn over the head and over the ears, or inserted in the outer ears.

There are two methods used by electronic hearing protection to reduce loud noises. One is the peak clipping method that uses a mechanism to detect loud sounds and automatically cut them off. The other method uses a compression technology that reduces a loud sound’s level into an acceptable tone.

The effectiveness of electronic hearing protection is determined by its Noise Reduction Rating (NRR). Most electronic hearing protection devices have a minimum rating of 19 decibels (dB). They are used in different situations involving heavy farming and industrial equipment, motor races, target shooting, and hunting.

Types of Electronic Hearing Protections

Electronic Hearing ProtectionsElectronic Hearing Protections

Kinds of Electronic Hearing Protections include the following:

Electronic hearing protection ear muffs

  • Electronic hearing protection ear muffs are worn over the head and over the ears.
  • They are made up of a sound amplifier that picks up low sounds and a protective system that dampens loud sounds like muzzle blasts.
  • They have an average Noise Reduction Rating (NRR) of 23dB.

Omni directional electronic hearing protection ear muffs

  • Omni directional electronic hearing protection ear muffs have four microphones (two in each ear muff) that pick up high-frequency sounds from all directions.
  • They are made up of a sound amplifier that picks up low sounds and a protective system that dampens loud sounds like muzzle blasts.
  • They have an average Noise Reduction Rating (NRR) of 29dB.

Electronic hearing protection radio ear muffs


  • Electronic hearing protection radio ear muffs have built-in AM/FM radios.
  • They allow landscapers, sports anchors, and construction workers to listen to their favorite radio stations while keeping their ears protected from loud, industrial sounds.
  • They use the peak clipping technology.
  • They have an average Noise Reduction Rating (NRR) of 22 dB.

Behind-the-ear electronic hearing protection aids


  • Behind-the-ear electronic hearing protection aids look like traditional hearing aids.
  • They are worn behind each ear and fitted snugly in each ear canal.
  • They are made up of a compression circuit that dampens impulse sounds and a sound amplifier that picks up low sounds and translates them into audible levels.
  • They have an average Noise Reduction Rating (NRR) of 29dB.
  • They come in one size that can fit all.

Choosing Electronic Hearing Protections (Buying tips)

NRR level: Choose an electronic hearing protection device with an acceptable Noise Reduction Rating (NRR) of at least 20dB. This rating offers adequate protection against everyday loud noises. However, if your work requires you to be continually exposed to gunshots, chainsaw grinding, and other industrial noises, look for one with a higher NRR.

ENC technology:
If you are frequently exposed to the low-frequency sounds from motors, fans, and engines, choose an electronic hearing protection device that uses the Electronic Noise Cancellation (ENC) technology. This technology uses a microphone for measuring an incoming sound to determine its loudness. If it is too loud, the device produces anti-noise sound waves to reduce the noise level of the original sound.

Comfort:
For a comfortable fit, choose electronic hearing protection ear muffs with an adjustable headband. This feature allows you to adjust the headband size to make the ear muffs rest properly over your ears. Make sure the headband and ear muffs are padded to reduce the pressure on your head and ears especially during extended wear.

Portability: For portability, look for electronic hearing protection ear muffs with a collapsible headband for easy storage in your handbag or backpack. You can also look for handy ear plugs that come in a compact carrying case.

Safety information

Clean the ear plugs before and after each use when using behind-the-ear electronic hearing protection aids to remove accumulated dirt and earwax that can cause ear infection.
Ear plugs are for personal use. Avoid sharing them with others unless necessary.
