One of the most common causes of hearing loss is loud sounds. The louder the ,sound,, the more damage it can cause to your hearing. We measure both ,sound, intensity and the perceived loudness of sounds using the decibel scale.A doubling of perceived loudness is represented by an increase of 10 decibels, although the actual ,sound, energy increase represented is much greater than that.
Earplugs, are ,often, used for noise protection when a consumer is going to be exposed to consistent or very loud ,sound, levels. Many people suffer from hearing loss, and while some hearing loss is age-related, other hearing loss is based on noise exposure.
provide protectors which cut out too much noise - this can cause isolation, or lead to an unwillingness to ,wear, them; make the use of hearing protectors compulsory where the law doesn't require it; have a 'blanket' approach to hearing protection - better to target its use and only encourage people to ,wear, it when they need to.
If you are trying to manage with bad quality or bad fitting earplug, you are doing more ,harm, than good. The performance of a hearing protection earplug or earmuff is indicated by a Noise Reduction Rating (NRR). The typical range for hearing protection is from 15 to 35 decibels of ,sound, reduction.
She said: ‘Many motorcyclists are not aware of ,the dangers, of riding without hearing protection while others may have tried ,wearing, foam ,ear plugs, but didn’t like them. These cheaper ,ear plugs, do a good job of blocking out ,sound, but can ,often, place the rider in a ‘bubble’ and make them feel removed from the environment around.
Therefore, it is wise to check how ,often, you are planning on using the ,earplugs, or have used them and to decide based on that whether they need to be replaced. To complete the overview of the lifespan of ,earplugs,, we are happy to supplement the information with the usage frequency and lifespan of foam ,earplugs, and custom-made ,earplugs,.
