Employer’s liability regarding noise induced hearing loss
Employers in Ireland have a legal duty to protect workers from excessive noise exposure under the Safety, Health and Welfare at Work Act 2005 and the Safety, Health and Welfare at Work (General Application) Regulations 2007, including the provisions relating to workplace noise.
Where workplace noise reaches certain levels, employers must:
- Assess and monitor noise exposure risks.
- Implement measures to reduce noise exposure.
- Provide suitable hearing protection where necessary.
- Provide information and training regarding noise risks.
- Arrange appropriate health surveillance, including hearing assessments, where employees are exposed to significant noise levels.
Workers in industries such as aviation, agriculture, construction, forestry, manufacturing, engineering, mining, transport, and heavy industry are at an increased risk of developing noise-induced hearing loss, tinnitus, and other hearing-related conditions.
Failure to implement appropriate safety measures may leave an employer liable where an employee develops occupational hearing damage.
Common causes of hearing loss
The following conditions commonly arise from prolonged or excessive workplace noise exposure:
1. Tinnitus
A persistent ringing, buzzing, hissing, or humming sound in one or both ears.
2. Acoustic shock syndrome
Damage caused by a sudden loud sound, explosion, impact noise, or repeated exposure to high-intensity sounds through communication headsets.
3. Occupational deafness (noise induced hearing loss)
Repeated exposure to excessive workplace noise can permanently damage the sensory cells of the inner ear, resulting in partial or complete hearing loss.
Where liability is established, compensation may be available for:
- Pain and suffering
- Loss of hearing
- Tinnitus
- Psychological impact
- Medical expenses
- Hearing aids and replacement costs
- Specialist equipment and adaptations
- Loss of earnings
- Future care requirements
Industries with a high risk of work-related hearing loss
The following sectors are commonly associated with occupational hearing loss:
- Construction
- Road drilling
- Mining
- Engineering
- Manufacturing
- Shipyards
- Agriculture
- Aviation
- Transport and logistics
- Metal fabrication
Workers in many other industries may also be exposed to harmful levels of workplace noise and may be entitled to pursue a claim where hearing loss can be linked to their employment.
Noise induced hearing loss claim process
1. Speak to a solicitor
Our experienced workplace injury solicitors can assess your circumstances, advise whether you may have a claim, and guide you through the process.
2. Submit an application to the Injuries Resolution Board (IRB)
Most workplace injury claims must first be submitted to the Injuries Resolution Board (IRB) before court proceedings can be commenced.
Examples include:
- Workplace injuries
- Occupational hearing loss claims
- Public liability accidents
- Road traffic accidents
Medical negligence claims and certain other categories are generally excluded.
3. Gather evidence and medical reports
Your solicitor will obtain:
- Audiology reports
- ENT consultant reports
- Employment records
- Noise exposure records
- Witness statements
- Medical records
These documents are used to support your claim.
4. Defendant’s consent
Once the application is submitted, the IRB formally notifies the defendant.
The defendant has 90 days to consent to the IRB assessment.
- If consent is given, the assessment proceeds.
- If consent is refused, the IRB issues an Authorisation allowing court proceedings to commence.
5. Assessment of the claim
Where the claim proceeds through the IRB, compensation is assessed based on:
- Medical evidence
- The Personal Injuries Guidelines
- Financial losses arising from the injury
If both parties accept the assessment:
- The IRB issues an Order to Pay.
If either party rejects the assessment:
- The IRB issues an Authorisation.
- Court proceedings may then be commenced.
Statute of Limitations
For occupational hearing loss claims, the limitation period is generally two years less one day from the date of knowledge.
The date of knowledge is the date when a claimant knew, or ought reasonably to have known, that:
- They had suffered a significant hearing injury; and
- The injury was attributable to workplace noise exposure.
In many cases, this will be the date of an audiology or ENT diagnosis rather than the date of the original noise exposure.
Because determining the date of knowledge can be complex, legal advice should be sought as soon as possible.
Employer’s duty of care
At common law, employers owe a duty to provide:
- Competent staff
- A safe workplace
- Safe equipment
- A safe system of work
In addition, the Safety, Health and Welfare at Work Act 2005 requires employers to take all reasonably practicable steps to protect employees from foreseeable workplace risks.
For workplaces involving significant noise exposure, employers should implement measures such as:
- Quieter machinery and equipment
- Noise-reduction engineering controls
- Acoustic barriers and sound-absorbing materials
- Reduced exposure times
- Rotation of staff where appropriate
- Provision of hearing protection
- Regular hearing assessments
- Noise monitoring and risk assessments
- Employee training on noise hazards
Failure to implement appropriate noise control measures may give rise to liability where hearing damage occurs.
Frequently Asked Questions
What noise levels can give rise to a hearing loss claim in Ireland?
In Ireland, the Control of Noise at Work Regulations set specific workplace noise thresholds.
Employers must take protective measures where exposure reaches 85 dB(A) as a daily or weekly average.
Workers who develop hearing loss following prolonged exposure to excessive workplace noise may be entitled to bring a claim where adequate protection was not provided.
How is noise induced hearing loss diagnosed for the purposes of a claim in Ireland?
Noise-induced hearing loss is typically diagnosed through audiological testing, including pure tone audiometry.
An audiologist or ENT consultant will assess the degree of hearing loss and prepare a report addressing whether the condition is consistent with occupational noise exposure.
Can I claim for tinnitus associated with noise-induced hearing loss?
Yes. Tinnitus is commonly associated with workplace noise exposure and can form part of a hearing loss claim. Compensation may increase where tinnitus significantly affects sleep, concentration, communication, or overall quality of life.
My employer has since closed. Can I still bring a noise induced hearing loss claim?
Yes. It may still be possible to pursue a claim against the employer’s liability insurer that provided cover during the period of exposure.
Occupational hearing loss claims are frequently brought many years after the original exposure occurred.
What is the limitation period for a noise induced hearing loss claim in Ireland?
The limitation period is generally two years less one day from the date of knowledge.
Because occupational hearing loss often develops gradually, the date of diagnosis or confirmation that the condition is work-related is often the key date for limitation purposes.
