Can AuditoryVoIP be helpful for a person with hearing loss?

Initial studies on hearing support for telephone use have shown that persons with slight to moderate heating loss can benefit from the algorithms developed at the Fraunhofer IDMT and can then understand telephone calls more easily and without effort. AuditoryVoIP offers different default settings for adjustment of the telephone signal to the needs of persons with typical age-related hearing losses of between 10 dB and 30 dB. Nevertheless, AuditoryVoIP does not have the functional scope of a hearing aid and is not a medical device.

Can I use the app with my hearing aid?

AuditoryVoIP was developed so that persons with slight to moderate hearing loss can again understand telephone calls easily and without effort. Whether AuditoryVoIP provides an additional benefit when using a hearing aid depends on the individual case. We recommend simply trying it out!

Should I adjust the app together with my hearing specialist?

A hearing test with audiometric measurement is not necessary for selection of your personal hearing settings. It is therefore not necessary for you to visit your hearing specialist. Please note that AuditoryVoIP does not offer the functional scope of a hearing aid, but simply allows improved speech intelligibility when making calls on a cell phone.

Can I also use AuditoryVoIP when making calls with headphones?

Yes, you can also use AuditoryVoIP with headphones. However, you may need to adjust your hearing settings to the sound characteristics of the headphones. We recommend simply trying it out!

What is adaptive signal processing?

Adaptive signal processing means that every incoming telephone signal is first analyzed and then adapted to the individual setting. As a result, quiet conversations become understandable again, but loud signals do not become too loud. In addition, only the frequencies in the signal are adapted that do not match the desired sound pattern. In contrast to this, an equalizer always emphasizes certain frequency ranges independently of the input signal. If the high frequencies are emphasized, for example, an equalizer can make a shrill output signal sound even shriller.

What is the difference between loudness and volume?

Volume is the physically measured sound energy value, while loudness is the sound level perceived by a person. Doubling the sound energy is not perceived as being twice as loud, for example. With typical age-related hearing loss, quiet sounds are not heard as well or possibly not at all, whereas loud sounds are often perceived as being too loud.  The signal processing system developed for AuditoryVoIP therefore adapts every telephone signal to the individually preferred loudness.

What is VoIP/SIP?

VoIP stands for Voice over Internet Protocol, a technical protocol for telephone calls made using the internet. An additional protocol is needed to make a telephone call with VoIP, the Session Initiation Protocol, or SIP for short. A so-called SIP provider offers you can access service for internet telephony.

What must I do in order to use an SIP account?

You will find a large number of SIP providers with different plans and offers on the internet. When you register with the SIP provider of your choice, in addition to your telephone number and access data, you will also receive the address of the SIP server which you need for registration of your account in the app.

Where can I find my SIP access data?

After registration of an SIP account, you will normally receive your access data by email. The data may also be provided online in your user account on the provider's website. Ask your provider in case of doubt. To register your SIP account in the app, you need your user name and password and the server address of the provider.

Can all phone numbers be reached with AuditoryVoIP – both in mobile and landline networks?

Using an SIP connection, you can make calls in all networks with AuditoryVoIP and also receive calls from both landline and mobile networks. Depending on provider, the only exceptions may be premium service numbers or emergency call numbers. Ask your SIP provider in case of doubt.
