With two major motoring events coming up in September, Hearing Protection & Communication (HPC) has warned car fans to consider suitable hearing protection – especially for children.
The Festival of Motoring South Africa at Kyalami is just around the corner (September 1 – 4) and the Speed ‘n’ Sound MotorEx at the Ticketpro Dome follows just two weeks later (September 16 – 18). At both, motoring enthusiasts in Gauteng will be able to get up close to some of the most exciting and powerful two- and four-wheel machinery in the land.
But the downside of all this is noise. Some of these machines will definitely generate extremely high noise levels – in some instances probably well above 120 decibels.
Normal speech is about 60 dB and because of the way sound is measured, a 3 dB change represents a doubling of the sound pressure level. A jet engine at take-off measures about 140 decibels, as does a gunshot from a small calibre handgun. Exposure to noise greater than 145 dB can cause permanent physical damage and unprotected exposure to decibel levels above 165 is virtually certain to damage a person’s hearing – instantly.
Explains Heinz Böse of HPC: “Noise levels from performance or competition engines can rapidly rise to a point where it exceeds a safe threshold and even short-term exposure to these levels can not only cause pain but also lasting damage. Sensitive young ears require extra protection and we recommend something like the Peltor Kid earmuffs when in a noisy environment. While designed primarily with music and entertainment in mind, they’re equally useful when around revving engines.”
Peltor Kid earmuffs are tailor-made for little ‘uns. Apart from the striking pink and neon green colours, features include wide, liquid-filled sealing rings for minimal contact pressure, a low profile headband, spacious inner cups, hygienic replaceable inner cushions, and a slimline design. Their Attenuation Rating (SNR) of 27 dB means they are more than capable of keeping sound pressure at an acceptable level.
Peltor Kid earmuffs can be purchased at good gunshops or, alternatively, on-line from www.hpc-peltor.co.za . Recommended retail price is R395.
