Soundshield - Digital Acoustic Shock Protection Device

Long periods of exposure to loud noise can effect the hearing of a telephone headset wearer. Soundshield 3G technology ensures headset wearers are exposed to a consistantly safe level of volume, actively adjusting sound levels to meet the strictest workplace daily noise exposure guidelines.

Soundshield prevents acoustic shrieks or high pitched tones from reaching the ear of a headset user, by detecting and instantly rejecting these shrieks within 16-32 milliseconds. Acoustic shrieks can potentially cause injury known as acoustic shock syndrome.

Soundshield is installed between the headset and the telephone console and is powered by 240V mains supply. Soundshield contains software which is programmable to work with all current and future headset models and PABX systems on the Australian market.

How does it work?
It Detects and Rejects Acoustic Shrieks The Soundshield's most innovative feature is its ability to recognise and eliminate 'shrieks' - high pitched piercing sounds. A dual-band 'shriek rejector' tracks and simultaneously suppresses up to two of these sounds while preserving consistent voice quality and intelligibility to the caller. Suppression occurs so quickly that the distressing and potentially damaging shriek is turned into a barely audible brief sound pip. This feature enables the operator to continue conversing, even if the fault in the phone network persists.

It Limits Exposure to Loud Noise
Unlike conventional analogue amplifiers on the market today, Soundshield has the ability to limit receive noise to a configurable acoustic ceiling of 80, 85 or 90 decibels. This means that the headset user will never be exposed to noise louder than the acoustic ceiling irrespective of the volume settings, loud voices, etc.
