Acoustic Shock
Acoustic Shock Syndrome occurs when a headset user is exposed to an acoustic shriek. It has become more common with the increase in telephone traffic and the growing number of call centres with dedicated operators around the world.
Preventing Acoustic Shock is available in two forms. The first is via a Soundshield protective device as below:

Soundshield equipment is designed and manufactured in Australia by Polaris and 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.
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.
The second method of protecting against acoustic shock is via headsets with a built-in ActivGard™ shock protection:

The products from Sennhesier offer the same level of protection, conforming to the G616 standard, and are the perfect choice for cost-efficient solutions for large and small business and government departments.
