Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many claims for hearing loss have there been in the (a) British Army and Army Reserve, (b) Royal Air Force and Royal Air Force Volunteer Reserve, (c) Royal Navy and Royal Navy Reserve, excluding the Royal Marines and (d) Royal Marines and Royal Marine Reserve for injuries sustained since the implementation of the Tactical Hearing Protection System programme.

The implementation of the Tactical Hearing Protection System programme took place between April 2015 and September 2016.

The number of Noise-induced hearing loss claims brought by current and former Service personnel is reported in the Ministry of Defence common law compensation claim statistics.

The breakdown of Service is not readily available. This does not include claims made via the Armed Forces Compensation and War pension schemes as providing breakdowns would require information from three different data systems to be combined and individual files to be manually reviewed which would incur disproportionate cost.

It is not possible to identify if claims relate to the Tactical Hearing Protection System.
