Our ears are intricate and extremely delicate instruments. Much like a person’s eyesight, once the hearing has been damaged, it cannot be reversed. It is vital, therefore, to protect hearing from the damaging, long-term effects of noise at work.

A custom approach to hearing protection
By
on 11 February 2020
This may seem obvious, but our research, undertaken by Opinium on behalf of Specsavers Corporate Eyecare in February 2019 among more than 500 senior decision makers in UK businesses, reveals that one-third (34 per cent) of employees who require hearing protection for work purposes are not provided with it by their employer.
Noise levels
It is clear that avoiding loud noises and controlling noise levels is the best way to avoid damaging hearing. Hearing damage can start from around 85 decibels (dB) – that’s about the top end noise of a busy street, or the average lawn mower – if exposed to it for eight hours or more without hearing protection. After 85dB, for every noise increase of 3dB, the exposure time cuts in half. For example, it is only safe to be exposed to 88dB sound levels for up to four hours, 91dB for only two hours, and so on. By 112dB – about the volume of a leaf-blower or chainsaw – damage to hearing can occur in less than a minute.
Responsibility
Under the Noise at Work Regulations (2005), it is the responsibility of employers to protect their employees from exposure to excessive noise and noise-induced hearing loss. In our research, some employers themselves acknowledged that they are not providing the necessary hearing protection, and by failing to do so, they may be putting their employees’ hearing at risk.
The employer should undertake a noise assessment to determine the correct hearing protection required.
This will depend on several factors, including the level of noise and the amount of exposure an employee has to it. It is also the employee’s responsibility to make sure they use the hearing protection provided.

Instant fit
Advances in technology mean the latest generation of instant-fit devices are now more effective and comfortable than ever. They are reusable and often designed for use in specific environments, like swimming, sleeping and riding a motorbike. However, they are not necessarily the best option for occupational noise protection and are best reserved for occasional leisure and DIY use.
Custom fit
Custom-fit devices are aimed at providing protection at work or in more specialised environments. Produced from an impression taken of the ears, or from 3D scanning, custom-fit hearing protection provides an individual with comfortable fit and guaranteed levels of protection.
Made from soft, medical-grade silicone, the best custom hearing protection is hardwearing and the bespoke fit means employees can wear them for longer than standard ear plugs, with greater levels of protection and comfort. Specialised hearing protection products are designed to protect the ears but also allow important sounds, like voices, to be heard clearly.
Only a quarter of employers provide custom-fit hearing protection
Our survey also looked at the types of hearing protection offered:
• Overhead earmuff 42 per cent
• Foam earplug 37 per cent
• Custom-moulded earplug 26 per cent
• Ear canal caps 21 per cent
• Flanged earplug 20 per cent
• Integrated earmuff 18 per cent
• Banded earplug 17 per cent.
Custom-moulded ear plugs are generally accepted to be the most effective solution for hearing protection, yet these are provided by just a quarter (26 per cent) of employers. While it is good to see that at least some hearing protection is being offered, employers should consider whether what they have provided is adequate.
Avoidable loss
Poor hearing is not something that is inevitable with old age. Nor is loss of hearing something that only affects older people. There are many factors that contribute to hearing loss, the most common being exposure to noise. This may be as slight as working around computer printers or next to an air conditioner, depending upon the amount of time spent in the vicinity of the noise.
It is important, therefore, that employers consider all employees and working roles. Although employees using heavy machinery in a manufacturing environment may be the obvious candidates for hearing protection, low-level noise hazards must be kept in mind too.
Hearing loss can have a profound effect on those who are affected. It can make conversations difficult and lead to isolation. Hearing protection is not, therefore, a matter of health and safety alone, it is also hugely significant to the wellbeing of employees.

Changes to ISO management standards: start preparing now
By Dr Keith Whitehead, British Safety Council on 08 August 2025
The key ISO management standards setting out best practice frameworks for effectively managing occupational health and safety, environmental and quality risks and opportunities are undergoing major revision, so it’s essential businesses start planning now to meet the new requirements in order to maintain their certifications under the relevant standards.
Inclusive, compliant evacuation planning: why training and maintenance matter
By Evac+Chair on 07 August 2025
Those responsible for business premises should provide assistive equipment to ensure the safe and efficient evacuation of people with mobility impairments. However, it is crucial that this equipment is regularly maintained and that staff are thoroughly trained in its use – otherwise, confusion and potentially fatal delays can arise in an emergency.
A step ahead: how the right safety footwear reduces workplace slips, trips and falls
By Simon Ash, HAIX on 06 August 2025
Safety footwear can prevent slip, trip and fall injuries, but it’s essential to consider other factors that could positively or negatively affect wearer comfort, such as breathable materials, waterproof qualities and boot weight.
