Setting and verifying the frequency response of a hearing aid remotely for adults during periods of restricted service delivery has been jointly produced by BAA Service Quality Committee and BSA Adult Rehab Interest Group.
This guidance focuses on the practicalities of setting and verifying the frequency response of the hearing aid entirely remotely.
This guidance has been developed to be used in conjunction with other guidance including A Guide to Remote Working in Audiology Services During Covid-19 and Beyond, May 2020, produced by Manchester Centre for Audiology and Deafness (ManCAD) and BAA Service Quality Committee, and the British Society of Audiology guidance on probe microphone measures (BSA, 2018).

Following the release of this Remote Guidance, a Practice Guide presentation has been prepared by Perindi Patel at Shropshire NHS Audiology Services. Perindi has kindly allowed this to be shared with fellow audiologists. Open presentation slides:

Attaching a thin tube BTE to a HA1 coupler (Interacoustics). This is a photo of a RIC but technique is the same as for a thin tube BTE
For the thin tube also add putty midway along the tube to reduce tube resonance
Departments will likely be more familiar with measuring RECD’s with an occluded mould and HA2, largely because of its use in paediatric audiology (see page 12). However for adult ears, particularly when considering a remote fitting pathway, there are reasons why the document focuses on the use of a HA1 for both RECD measures and subsequent coupler verification :
The HA1 method is gold standard for an adult RECD and verification due (see document). However, it’s understood that coupling a mould/thin tube to a HA1 can be more difficult than coupling via a HA2 method. Here are a few tips to support a stable, repeatable frequency response when using a HA1 during coupler verification.
Remember to add a small piece of putty to a thin tube during verification, to act as a dampener (as though against the head in situ) and avoid additional resonance.
