Our ability to listen to is really important to us, it allows us to hear our favorite music, and it enables us to hear voices that can signal the presence of potential problems. But the most essential feature of our ability to hear is the ability it offers us to listen to and effectively convey with different individuals, to hear and to learn. One of the primary origins of hearing difficulties is due to being exposed to extreme sound impulse.

We are all continuously subjected to loud noises, at home while we are doing work in the lawn with a garden tractor, while cleaning the house with a vacuum cleaner or perhaps while preparing food with a food processor or blender. Our ears can usually tolerate it most of the time however when subjected quite often, specifically to serious excessive sounds such as the noise of loud motors from the factory while doing work or the tremendous tone from a rifle during target shooting may result to quick long term hearing reduction, and as soon as the injury is done it could not be repaired.

That's precisely why we need to take good care of our hearing, by wearing hearing protection gears and accessories. Depending on where you plan to use it, you can purchase from various forms of hearing protectors, for example the normal earplugs and earmuffs or head phones. They function by simply lowering both the low and high frequency noises to a fairly good level, usually to about 22 dB for earplugs and 27 dB for earmuffs or head phones. A number of producers have brought it to the next degree and identified a solution to attenuate various sound frequencies in different ways by making use of a combination of several components for several uses.

For dangerous sounds like when you are in a shooting range specifically if you are using high caliber rifles like shotgun, you need a more cutting-edge hearing protector similar to the electronic hearing protection. This advanced system is specially designed to reduce only the excess tone generated at certain pitch, including the tone of the rifle and aircraft engines and not the noise from a breaking glass, horn from a passing automobile and the voice of another people.

This is carried out by installing a microphone and amplifier to attenuate the excess noise and amplify poor sounds before it plays back to the built-in speaker almost at the same time. It's like a very fast repeater but filters the noises first prior to feeding it to the user. It also has a sound control so you can correct the sound originating from usual discussion and the sound indication of impending dangers. Both cups have its individual microphone to imitate the sound of the environment in full stereo audio, just like you would ordinarily hear it in actual life. The unit is power by four 1.5 volts AAA batteries which are great for about 200 hrs of use. One of the well known manufacturers that most police force, military and shooters preferred is Peltor which is produced by 3M. They have a whole line of hearing protection from very simple earplug and earmuff to a more complicated electronic head phones.

Basic Info about Sound and Noise: Sounds are vibrations that run through substances like air and water as sound waves. All sounds possess two characteristics, the amplitude which determines the loudness of the sound and the frequency which determines the tone or pitch of the sound. Loudness is referred to as sound level or sound intensity that is measured in Decibels (dB). A whisper has a sound about 20 dB, common conversational speech is around 60 dB and a pneumatic drill is generally over 110 dB. Discomforts develop at about 120 dB and pain can be experienced at throughout 120 dB.
