The long, plastic, trumpet-shaped vuvuzela was found to emit an ear piercing noise of 127 decibels – louder than a lawnmower (90 decibels) and a chainsaw (100 decibels). Extended exposure at just 85 decibels puts us at a risk of permanent noise induced hearing loss. When subjected to 100 decibels or more, hearing damage can occur in just 15 minutes.
The most popular cricket fan instruments from across the world were tested in a sound proof studio as part of Hear the World, a global initiative by leading hearing system manufacturer Phonak to raise awareness about the importance of hearing and the consequences of hearing loss. The distance between the sound source and the testing device was 10 cm and the test was carried out using benchmark filter A under the IEC standard, as this represents actual hearing perception. The test series was monitored and logged by an audiologist from Phonak AG.
Second most harmful to our ears was the air-horn, popular with English Cricket fans, which exposes our ears to damage inducing levels of 123.6 decibels. This was followed by the drum, which reached a level of 122 decibels. Popular with supporters on the stands as well as being used on the pitch, the referee’s whistle was the fourth most harmful to our ears at 121.8 decibels, but passionate fans alone can be just as problematic - two singing supporters reached 121.6 decibels.
It’s not just while sitting in the stands at a match that hearing damage can happen. Our ears can be exposed to damaging noise levels when in the pub surrounded by excited cheering fans, or even while at home, with people often turning the sound on their television up very loud in order to create an atmosphere when watching from their sofa.
Advice to fans would be to enjoy the atmosphere that the World Cup creates, but also to consider their hearing. Why not give their ears a break from the noisy atmosphere at half time, or if they are one of the lucky ones heading to India, remember to pack some earplugs - once the damage is done it is irreversible so prevention is key.
Phonak said, Of course the sound of the crowd plays a major part in creating the atmosphere in a cricket stadium. But people should remember that prolonged exposure to loud noises can have a big impact and therefore it is imperative that we take conscious measures to protect our hearing before it’s too late.
