To avoid noise-induced hearing problems, hearing protection is essential. Appropriate protective devices minimise the amount of noise energy that reaches the eardrum and causes harm. The most prevalent forms of PPE are earmuffs or earplugs. Workers who may be exposed to noise values equal to or more than 85 dB averaging above eight hours must wear protective gear.
What can I do at work to safeguard my hearing?
To prevent noise-induced hearing loss (NIHL) the most efficient way is to completely remove the noise-producing source or minimise the noise of the source using engineering techniques. Unfortunately, in several cases, these steps aren’t feasible. Labourers in such environments may need to use hearing protection to decrease the quantity of noise that reaches their ears.
What factors should I consider before purchasing hearing protection?
Hearing protection is quite a matter of choice that is influenced by a variety of criteria such as noise level, convenience, and the sound protector’s compatibility for both the employee and the workplace. The hearing protection should, above all, achieve the necessary noise reduction. When hearing protection is required, it is better to offer a variety of various varieties to select from. If noise is infrequent, earmuffs are preferable since removing and reinserting earplugs might be cumbersome. If the noise or sound levels are close to or above the occupational exposure limits, then they must wear hearing protection. The occupational exposure limit in most countries is 85dBA. If worn appropriately, hearing protectors limit exposure to noise as well as the danger of hearing problems.
Whenever hearing protection is essential, a comprehensive hearing protection programme should be put in place. Noise monitoring, noise reduction measures, hearing protector availability, personnel education and skills, audiometric examination, upkeep, certification, records management, and programme evaluation is all part of a hearing conservation programme.
Hearing protection’s efficiency is considerably diminished if somehow the hearing protectors not fitting well, are not placed or worn properly, are used only seldom, or are unplugged even for a brief moment. Hearing protection must not be altered to retain its efficacy. Radio/music earbuds or headphones are not an alternative for hearing protection and should never be used in situations when hearing protection is necessary.
Choose hearing protection that meets the following criteria
- Provides suitable noise suppression or shielding. Consult the manufacturer’s documentation.
- Compatibility with additional personal protection equipment or telecommunications devices, that may be necessary.
- Should be comfy enough to wear.
- Suitable for the dynamic workplace’s weather and humidity.
- Fulfil communications and perceived loudness requirements (e.g., should be able to hear alarms or warning sounds).
What kinds of hearing protection are there?
- Around the ear canal, earplugs are placed. Pre-moulded, deformable, rolldown foam, squeeze, and custom moulded are all options. Earplugs are offered in three types: single-use plastic, recyclable, and bespoke.
- Semi-insert earplugs are made up of two earbuds kept together by a stiff strap at both ends of the ear.
- Sound-attenuating fibre, soft ear pads that best suit around the ears and firm exterior cups make up earmuffs. A headband holds them all together.
Among the most appealing features of these ear protection gear is they are not required to be custom-built. The majority of models are full size, however, some may be simply adjusted to suit the wearer’s head tightly. They’re superficial to spot and next to impossible to lose due to their size. They not only protect personnel from loud noises, but they also maintain their ears warm, making them excellent for labourers and groundskeepers who have to deal with chilly temperatures on their job. If loud noise is not present, rechargeable electronic ear muffs use microphones to let ambient noises in. The mic rapidly attenuates when loudness is sensed, protecting the user. These are very beneficial for shooting and hunting. Modern automation muffs use directional mic’s to create a more realistic hearing experience, as well as audio input ports to let the wearer enjoy music or attend a call.
- reduced variation in attenuation among consumers
- made to suit most head sizes in one sizing
- they are plainly visible from a distance.
- not often lost or misplaced
- Even if you have a small ear infection, you can wear it.
