Polaris Amplifier Soundshield 4G 5 year manufacturers warranty Soundshield is a digital Acoustic Shock Protection Device designed and manufactured in Australia using the latest DSP (Digital Signal Processing) technology. 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. Without the protection of Soundshield acoustic shrieks can potentially cause injury known as acoustic shock syndrome. Long periods of exposure to loud noise can affect the hearing of a telephone headset wearer. Soundshield 3G technologies ensures headset wearers are exposed to a consistently safe level of volume, actively adjusting sound levels to meet the strictest workplace daily noise exposure guidelines. Soundshield 4G is world renowned as the safest solution for headset users. Soundshield 4G has been designed to provide Contact Centre Headset Users with the highest level of acoustic protection while maintaining excellent voice clarity and intelligibility. In addition to this, the new Soundshield's intuitive colour touchscreen provides users with all the essential call controls right at their fingertips.

Acoustic shock is a world-wide phenomenon that has been increasing in line with the expansion of the contact centre industry. With the proliferation of contact centres came a dramatic increase in the use of headsets which are a major contributing factor in the incidence of acoustic shock syndrome.

Acoustic Shock Syndrome occurs when a headset user is exposed to a sudden and unexpected loud noise or high pitched sound, usually in the frequency range 1kHz - 4kHz.

It is the sudden and unexpected onset of these sounds which is the cause of acoustic shock. Using a headset increases the risk of dangerous exposure to high pitched sounds because a headset, unlike a traditional phone handpiece, cannot be dropped or quickly removed from the ear as soon as the noise is heard.

Simply being exposed to constant loud noise through a headset cannot cause acoustic shock. This may cause long term hearing damage, but not acoustic shock injury.

Examples of high-pitched tones or acoustic shrieks:

  • Incorrectly dialled fax machines.
  • Maliciously generated noises - screaming or blowing a whistle down the line.
  • Feedback or oscillations between a cordless phone and its base station.
  • Mobile phone interference.
  • Faults on the telephone line that cause loud shrieks from the Public Switched Network.
  • Callers dropping their handset on to a desktop.



Symptoms of Acoustic Shock

The typical symptoms of Acoustic Shock are:

  • Ear-ache and nausea.
  • Headaches, jaw and neck pain.
  • Hollow feeling in the ear.
  • 'Fluttering' noise in ear, leading to poor balance.
  • Burning sensation to face and head.
  • Tinnitus (ringing in the ear) and hearing degradation over time.
  • Permanent sensitivity to loud noises in general, thus affecting lifestyle.
  • Where inner ear membranes have been otherwise weakened (by ear infections or diving trauma) acoustic shock can cause tearing of the inner ear membrane.
  • Stress and apprehension about the likelihood of a recurring incident.

Affected workers may then feel hypersensitive to loud sounds that previously would have caused no problems. The fear that a shriek might reoccur lowers their threshold even further, putting them at greater risk of injury if it happens again. This is even likely to affect co-workers, who may be apprehensive about the likelihood of an incident.

The problem of Acoustic Shock is not limited to any particular telephone or headset type, or any particular telecommunications network or equipment. High pitched tones are random and often cannot be traced or prevented from recurring.
