Most hearing protection does have a set life expectancy and will ‘expire’ after a set time, even if not in use. A typical shelf life for hearing protection is five years, or lower for more budget options. This is how long hearing protection can last for before needing to be replaced.

A common recommendation from Occupational Health Physicians is ‘recommend wear double hearing protection’. What they are saying is that the person concerned wears two sets of hearing protection but this often has no link to the findings of the noise assessment.

Despite ear plugs having quite a low per-pair cost, that cost can soon mount up and it is tempting for employers to limit how many pairs people can use in a given period, or the employees themselves choose to reuse them, but this is not always a good approach and can also be a false economy.

Over-protection often comes from well-meaning employers buying the strongest hearing protection they can find - hearing protection with the highest SNR. They mean well but it often actually increases risk and for the employer, means more of the money they spend on hearing protection is wasted.

Hearing protection comes in a very wide range of prices, but is price consistent with ‘better’ hearing protection?

Sometimes people will say using ear plugs causes them to get ear infections, but do ear plugs actually cause infections? Short answer, no. Dirty hands putting them in, that can cause an infection, but not the plugs themselves.

There is no exemption from the need to wear hearing protection for forklift drivers. High noise will have the same impact on them as on any other person. Their hearing will still be damaged by noise.

It is common to hear someone claim a medical exemption from the need to wear hearing protection at work, sometimes backed up with a note or letter from a GP, or sometimes self-claimed, but are medical exemptions from the need to wear hearing protection possible?

Noise levels can be very high when riding a motorbike - easily in the mid-90s dB(A) which can damage hearing. Ear plugs need to be enough to remove some of the noise but not isolate you from traffic, and they need to be soft and not painful under the helmet. These are some recommendations.

Can wearing ear plugs cause tinnitus when worn all day in a factory?

This is a common question for hearing protection, be it due to external noise from life in a town or city, shift workers trying to sleep when everyone else is awake, trying to sleep in hotels, or just with a partner who snores a lot.
