Super-keen birdwatchers chasing the glory of being the first to hear the cuckoo this year may be foiled — because their hearing’s not good enough.
Thousands of bird watchers have hearing loss which limits the range of sounds they pick up. So they miss the first note “cu” of the the-hard-to-spot cuckoo’s distinct call and could confuse it to similar sounding birds like the wood pigeon.
Mark Williams, our chief Audiologist from our Harley Street Clinic said: “In the majority of cases, hearing loss means people do not pick up the higher frequency sounds. This could mean that the birdwatchers will not hear the “Cu” in a cuckoo's call because it is in a high frequency. Only the “ckoo” sound is in their range”.
With secretive birds like the cuckoo, birdwatchers rely on identifying them by their song. As 10 million people in the UK have hearing loss, it is inevitable that a significant number of the RSPB’s estimated figure of three million UK birdwatchers will have impaired hearing.
So a bird spotting walk through a forest will be considerably less fulfilling for those who can’t hear clearly. For example, the wren and other woodland and garden birds – many of which are so shy that they are only heard but not seen on birdwatching trips - also sing in high frequencies
Friends were picking up birdsongs that I didn't hear at all
Staffordshire Bird Watcher, Steve Skeet said “I didn’t notice that my hearing was not one hundred per cent until I went on a trip with a group of friends. As we walked through the woods they were picking up birdsongs that I didn’t hear at all.”
Mark Williams said: “Modern hearing aids can restore the audibility of high pitch sounds for individuals affected by high pitched deafness".
“Systems achieve this by either selectively amplifying higher pitched environmental noises or, if the listener has completely lost their ability to hear, by simply processing high pitched sound at a lower frequency. This is known as frequency compression and if used correctly by a skilled audiologist, it can enable people with very poor hearing to hear sounds that would have previously been lost forever.
“Not only are people able to restore their hearing range and enjoy their hobby to the full, they’ll also be helping the cuckoo and other birds now on the threatened species “red” list. The more birds that are identified and reported, the more data organisations like the RSPB and BTO can use to help them.”
The Tinnitus Clinic has clinics throughout the UK
An important part of my mission at The Tinnitus Clinic is to share our knowledge of tinnitus; its causes, how to prevent it and what to do if you are suffering from the condition. This blog will go some way in achieving this aim.
