Ear plugs are designed to be inserted in the ear canal and are used to help protect your ears from the effects of noise. Although ear plugs help protect your ears they are not to be used as an alternative to controlling noise.

Under the control of noise at work regulation all employers must provide suitable hearing protection to employees where noise exceeds 80 dB (A).The SNR value is a European standard, the higher the SNR, the higher the level of noise attenuation provided by the earplugs. Remember that the SNR value is a guide only. Independent laboratories test earplugs to determine their SNR value. The SNR value can be used to compare the level of noise attenuation offered by different hearing protectors.There are many different types of ear plugs available and the type you choose depends on your personal needs.Type of Ear plugsDisposable ear plugs are normally made from expandable, slow recovery foam. They combine protection as well as comfort. They are designed to be thrown away after a single use and are available as individual earplugs or as a corded pair.
