The Comfort Digisystem is a set of digital communication systems for hearing implants. These systems help people with hearing loss to hear better in different environments. The system offers different microphones and receivers that can be used for different situations, including conversations, conferences, and phone calls. The technology, called SecureStream Technology, improves the signal-to-noise-ratio (SNR) up to 20 dB in noisy environments.

COMFORT DIGISYSTEM Digital communication systems for hearing implants Compatibility guide Why Comfort Digisystem and hearing implants? Three factors influence the signal-to-noise-ratio (SNR): background noise, distance to the speaker and reverberations. Those with normal hearing are able to understand speech, even if the noise level is around 6dB higher than the speech level. People with hearing loss, however, have lost this ability. They struggle due to deteriorated speech recognition performance in noise and a reduced dynamic range. In order to obtain acceptable speech intelligibility, people with hearing loss need an SNR that is 5-15 dB higher than people with normal hearing1. How can speech intelligibility and SNR be improved? Why Comfort Digisystem? Most ALDs which complement hearing aids or implants are based on a very simple principle: the sound is captured by a microphone that is positioned closer to the sound source than the hearing implant. The sound is then transmitted to a receiver worn by the user. The receiver transmits the sound into the hearing implant. Most ALDs use analogue transmission. Although this technology has undoubtedly been refined since its introduction, it still suffers from basic deficiencies, such as hum, signal loss and restricted range. 20 Signal-to-noise ratio in dB In order to improve speech intelligibility in noisy environments, a hearing implant is not enough. Several studies confirm that the use of assistive listening devices (ALDs) as a complement to hearing implants improves the speech recognition by up to 20 dB2. 15 10 5 0 90 80 70 60 50 40 30 Average hearing loss in dB Necessary improvement in signal-to-noise ratio for 50 % recognition of sentences (adults); (Killion 1997) Killion, M.

The technology is called SecureStream Technology (SST) and has several advantages: • T he dynamic range spans over more than 60dB. • Audio bandwidth of 100-7000 Hz. • The transmitted sound is crystal clear, without transmission noise or signal loss due to FSKmodulation (Frequency shift keying). • The sound is transmitted without time lag. • Long operating range (between 15-30 m). • The signal is scrambled, so it is secure from eavesdropping. Source: Delta Teknisk-Audiologisk Laboratorium, Denmark and internal measurement method. Digital technology also creates new possibilities for sound processing. Perceptual Speech Enhancement (PSE) is a unique and extremely powerful sound processing technology that enhances speech and reduces background noise. The result is an improved SNR of up to 20 dB in noisy surroundings with clear and natural speech reproduction.

The following products can be used: Conference Microphone DC20, Receiver DT10 or DH10. Landline telephone The TeleLink accessory is connected to a landline telephone and is used together with the conference microphone. The sound from the telephone is sent to the receiver worn by the person with hearing loss and from there directly into the hearing implant. The following products can be used: Conference Microphone DC20, TeleLink, Receiver DT10 or DH10. Mobile phone During a telephone call, the sound is sent via Bluetooth from the mobile phone to the microphone and from there to the receiver worn by the person with hearing loss. The receiver transmits the sound directly into the hearing implant. The following products can be used: Microphone DM80, Receiver DT10 or DH10. Pupil with teacher The teacher’s microphone picks up his/her voice and transmits it to the receiver worn by the pupil with hearing loss. Natural sound, without background noise, is sent directly into the hearing implant. The following products can be used: Microphone DM10, Receiver DT10 or DH10. Lecture The lecturer wears the microphone to pick up his/her voice. The sound is processed and sent digitally to the receiver worn by the person with hearing loss and directly into the hearing implant. The following products can be used: Microphone DM10, Receiver DT10 or DH10. Special school In a special school for children with hearing loss, all pupils and even some teachers suffer from hearing loss. The Microphone DM30 can be used as a push-to-talk microphone, teacher’s microphone and receiver. Pupils can understand what both the teacher and classmates are saying. At the same time, they can participate actively in any classroom conversation. The following product can be used: Microphone DM30 In the car In a car it is usually rather noisy. Here, several microphones are used, depending on how many people are sitting in the car.

The user´s speech recognition performance should be almost the same in both cases. • If not, use either the Programmer DT05 or the Gain Control of the Oticon Amigo FM-CI adaptor to optimize the output level of the FM-CI adaptor until almost the same performance is obtained. • Note: The R+M mode is recommended for use in quiet. The R mode provides the user with a good speech recognition performance in noise.
