Much of the music played at live music festivals includes a lot of bass sound and subsequently a high level of low frequency noise. Additionally, the use of visual effects on stage, such as fireworks, produces percussive noise which is also low frequency. It is for this reason that festival organisers, such as Glastonbury, have selected Howard Leight by Sperian's Laser Lite earplugs which are particularly effective at attenuating low frequency sounds, says the company.
Laser Lite single-use earplugs are made from self-adjusting polyurethane foam which expands to fit virtually every wearer, making them comfortable to wear. Their contoured T-shape also offers easy and comfortable insertion, whilst the smooth, soil-resistant closed cell-foam skin prevents dirt build up. Another advantage of Laser Lite earplugs is their vibrant colours which offer easily visible protection enabling employers to quickly identify when they are being used.
Another option especially suited to protecting the hearing of workers at live music events is Clarity 656 earplugs from Howard Leight by Sperian which are unobtrusive and lightweight, yet exceptionally effective. With a transparent body that makes them almost invisible when in use, Clarity 656 earplugs achieve a high level of acceptance from users that might be unwilling to wear less attractive and more easily visible hearing protection devices. With soft flanges and rigid stems, they are also easy to insert, further increasing their usage.
The Clarity 656 earplugs also incorporate Bilsom's patented sound management technology. This means that, although they are completely passive devices that require no power source, the level of attenuation they offer varies with frequency allowing them to combine excellent protection with convenience and ease of use.
Clarity 656 earplugs strongly attenuate hazardous noise, while allowing voice frequencies to pass through the earplug more effectively than in most earplug types. Users can, therefore, carry on conversations with ease, which can be an important benefit when, for example, they are used by staff at live music events.
