Astley was given two hearing aids – one was a receiver-in-canal, and the other an invisible-in-canal.
A survey carried out by Specsavers found one in three people recognised changes in their hearing over 10 years – but 57% did nothing to address it.
The same research found one in six blamed hearing the wrong song lyrics on struggling to hear, with 56% of them admitting they did nothing to get it checked.
Specsavers audiologist Gurleen Brar, who carried out Astley’s hearing test, said: “Specsavers understands that we all hear differently because we care for more ears across the UK than anyone else.
“We believe that everyone deserves to hear life in their own unique way, and we are determined to help close the 10-year gap that exists currently.
“The quicker we understand the way that we hear, the quicker we can act when we notice changes which will help minimise any long-term impact.”
