Significant better speech recognition

People with hearing loss require a more favorable signal-to-noise ratio than normal hearing people in order to communicate in complex listening environments. Hearing aids and cochlea implants allow people with hearing loss to hear and understand speech better. Although there are situations when a hearing aid is not enough to have good speech understanding. The latest microphone in the Roger family, Roger Table Mic aims to provide better speech understanding and intelligibility in meetings. Recent study shows significant improved speech recognition at 3 and 4.5 meters using Roger Table Mic.

How can speech intelligibility be improved for adults using conference microphones?

Being part of a community of colleagues at work is taken for granted by persons with normal hearing who participate in discussions and meetings. Meetings are important in life and often include small talk that may inspire and motivate participants.

But what is it like to take part in a meeting as a Cochlear Implant user?

 

The user´s experienced benefit by using Comfort Digisystem

In Sweden hearing loss is the most common disability, in general figures we can say that about 10% of the population has a hearing loss. The value is of course different in different age groups; according to Kochkin (www.betterhearing.com) 3 in 10 people over age 60 have hearing loss; 1 in 6 baby boomers; 1 in 14 Generation Xers already have hearing loss.

The problems with hearing loss seems to grow bigger, in 2008 1% of recruitants in the Armed Forces initial training in Norway had a hearing loss, in 2012 7% had a hearing loss. These persons are in the age 20 years and below

Wireless Transmission of Sound Without Disturbance or Dropouts

Over recent decades, hearing aids have become more technologically advanced, and today most incorporate noise reduction. However, it remains difficult to improve the signal-to-noise ratio with more than 3-6 dB (SNR) with a hearing aid alone.

To achieve the maximum benefit of hearing aids in all situations, a system with wireless digital transmission can be used to improve the SNR with up to 24 dB.

 

The Need for Conference Microphones

Being a part of a community of colleagues at work is to take an active part of informal and formal meetings. 20% of hearing aid users are dissatisfied with their hearing aids in large meetings. Comfort Audio produces two conference microphones to capture sound from short and long distances.

Each microphone incorporates Perceptional Speech Enhancement and Active Noise Reduction that can improve the signal-to-noise ratio (SNR) by up to 20dB.

 

Excellent speech understanding in high noise levels

A recent study by Professor Linda Thibodeau at the Callier Center for Communication Disorders, part of the University of Texas in Dallas, revealed that the usage of Roger systems in combination with hearing instruments resulted in significant improvements in speech understanding in noise at 65 to 80 dB(A) noise levels over traditional and Dynamic FM technologies. At 75 dB(A) there was an improvement of 54% over traditional FM.
