Now you can have hearing protection and clear communication at once

The Sensear technology sets a new benchmark in hearing protection and assisted listening. For the very first time Sensear has made clear communication possible in high noise environments (above 85db(A) where hearing protection is essential. Sensear has perfected the combination of speech enhancement technology and noise suppression technology integrated with a complex series of patented algorithms, producing a cutting edge innovation called SENS® technology. Sensear has integrated its revolutionary SENS® technology into a range of products that will radically change the way people communicate and protect their hearing in high noise environments.

Sensear’s SENS® technology is the only technology that can effectively distinguish speech from background noise. Sensear’s revolutionary solution combines an array of tiny microphones seamlessly connected to a small processor discreetly fitted within the products. The processor acts to distinguish speech from background noise via its cutting edge SENS® technology, selectively enhancing speech and simultaneously suppressing noise.

Post-filtering techniques are then used to further improve noise suppression and enhance speech. This is done in real time and at very low levels of power consumption. The background noise characteristics are retained, including binaural capability (the natural ability to decipher direction of any sound) while at the same time lowering noise to safe levels to ensure that the wearer remains aware of their surroundings.

The result is high quality natural speech played directly into the Sensear earmuffs or earplugs or optionally connected via Bluetooth® to mobile phone or two-way radio.

Sensear’s SENS®technology has the following advantages over traditional technologies:

  • Is the only technology effective in providing speech enhancement and hearing defence across all 3 noise
    classes - Impact, Continuous and Intermittent. SENS® technology is the most advanced on the market.
  • Remains consistently effective in high noise environments - above 85db(A) where current technologies
    struggle to perform.
  • It provides noise suppression while giving speech priority, ensuring that speech can still be heard while all
    other noise is suppressed. This unique capability includes impact noise.
  • Binaural capability allows the direction of all sounds, including speech and alarms to be safely heard.
  • Removes the need for annoying boom microphones.
  • Is the only technology to provide intelligible speech in the harshest background environments. These include
    noises associated with speech frequencies such as turbine noise.
  • Sensear has produced the world’s first electronic ear plug model.
  • Sensear devices meet European, US, Australian and NZ standards.


A new frontier for clear communication in high noise

Sensear’s research efforts have been applauded by industry, as the combination of academic excellence, persistence and field research delivers technology and products that will revolutionise communication and hearing protection. Sensear’s products have been designed “in the field for the field”. More than five years of research and development including extensive client trials with Global 500 companies has resulted in the commercialisation of Sensear’s SENS® technology, the first and only technology effective in enabling speech communication to be consistently heard above 85db(A) whilst providing hearing protection.

Sensear’s technology and products have all been developed using a strong methodology of research, consultation, development, laboratory testing and field trials. This approach has enabled delivery of highly functional products that meet the needs of industry and deliver innovative features and value. It has also yielded a world-first electronic ear plug, the SP1(x), and a price/performance curve that is superior to all competing products.

Speech Enhancement
Sensear’s revolutionary speech enhancement technology isolates and enhances speech in real-time, enabling users to hear speech clearly and safely in environments that until now has been impossible. Sensear’s speech enhancement technology is effective for mobile phone calls and two-way radio communication as it enhances the wearer’s speech and lowers background noise for the call receiver.
Noise Suppression
Sensear’s SENS® technology recognises the different properties of speech and background noise thereby allowing noise to be suppressed without distorting or blocking speech. The technology reduces background noise to comfortable levels while retaining the original sound characteristics of noise. This allows users to retain awareness of their surroundings for optimum safety.
Sensear’s x models incorporate Bluetooth® technology, enabling pairing and subsequent connection with mobile phones so that users can take and make mobile phone calls without removing hearing protection. SENS® technology + Bluetooth® means lower background noise for the call receiver, enabling natural and comfortable communication with the wearer.
