Polaris is launching a new model SoundShield. It is USB powered (i.e. does NOT require a power pack) and is said to have OPTIONAL software that can tell you when you have been protected from an acoustic event. Today, I connected a unit to two different XP computers. Not simultaneously of course. The Windows XP operating system could not recognise it. It looks like they have a way to go.

I will update this information as I find out more.

Polaris's SoundShield

SoundShield is an Acoustic Shock Protection device that uses DSP technology and a software platform to detect and reject high pitch tones and present a safe listening level to users of telephone headsets.

SoundShield was originally designed and developed over 3 years by leading audiologists, telecommunications and software experts from a collaboration between Telstra, National Acoustics Laboratories (NAL) and CRC for Cochlear Implant and Hearing Aid Innovation (co-developers of the Bionic Ear).

• Shriek Detection and Rejection
  SoundShield uses Digital Signal Processing (DSP) technology to detect and reject any high pitched tone or shriek whilst maintaining superior voice clarity and intelligibility. Up to two shrieks can be removed simultaneously within 16-32 milliseconds, well within the time limit to prevent hearing damage.
  
  
• Absolute Acoustic Ceiling
  SoundShield prevents all noises above an absolute acoustic ceiling of 90dB from reaching the user's ear. This level is 33dB below ACA Regulations. The absolute acoustic ceiling is downwardly configurable to 80dB or 85dB for use in call centre environments that are less noisy. Current ACA regulations allow a maximum of 123dB, however this level is currently being reviewed by the ACA/ACIF, and it is likely that a new standard for Acoustic Shock Protection devices will be created.
  
  
• Superior Voice Clarity
  SoundShield displays superior voice clarity and digital quality to that of existing headsets and analogue amplifiers which are limited to the functions of analogue technology. In an effort to reduce the level of loud noises, analogue amplifiers dampen noise levels but also display poor voice clarity.
  
  
• Automatic Listening Levels
  SoundShield provides the most comfortable listening level based on calculations of volume and tone over the previous six calls.
  
  
• Software Configurable
  SoundShield can be used with any headset brand and any host system. Its software is upgradeable to cater for any future headsets or host systems or to add further product features or developments. It features an on board serial interface for this purpose.
  
  
• User Protection Increases Confidence
  When SoundShield is in use, the green ring provides a certain level of comfort to the user, knowing they are protected from acoustic shock. This confidence in staff also reduces stress and apprehension about the possibility of an incident, while for Call Centre Managers, the liability and consequences associated with an acoustic shock incident are eliminated.
  
  
• Compliance
  SoundShield is completely compliant with all relevant standards of the Australian Communications Authority and ACIF.
  
  
• Contemporary Design
  SoundShield has been designed with a contemporary and ergonomically friendly look.
  
  
• Australian Designed and Manufactured
  SoundShield was designed by a collaboration of Australian companies, and will be manufactured and distributed by Polaris, a 100% Australian owned company.
  
  
• Five Year Warranty
  Polaris offers an unconditional Five Year Warranty on SoundShield. Each unit is produced to the highest standards, is attractive and durable and uses world first, state of the art technology. As SoundShield is a locally produced mainstream product, Polaris can guarantee ongoing technical support and the continuous availability of spare parts.
