About us

The Modernising Children's Hearing Aid Services (MCHAS) was the title of the research and training programme which introduced digital signal processing hearing aid technology into the NHS.

The programme ran from 2000  - 2005 and during this time all Audiology departments in England, received training and children are now routinely fitted with digital hearing aids. Alongside the introduction of new hearing aid technology, new fitting procedures and working practices were introduced.

Guidelines covering these procedures were written and are now accepted by the profession as standard quality practice.
