The persistent affairs over a longer period at the Tinnituszentrum Detmold clearly show:

  • The number of pupils with hearing impairments is increasing.
  • The number of young people suffering from Tinnitus is increasing.
  • More and more teachers complain about increasing hyperacusis going along with vocal overstressing.

The Audiovisual Noise Indicator is one possibility to antagonise this development.

The device is similar to a traffic light and evaluates the surrounding average noise level with a green, yellow or red signal.

Additionally, the red light can trigger a sound signal.

In September 2006 we provided 14 primary schools in Detmold with one Audiovisual Noise Indicator each. All relevant teachers and pupils have received a pedagogic introduction to the Audiovisual Noise Indicator.

After 10 weeks (November 2006) and after 26 weeks (February 2007) of active testing in class, the practical experiences were collected with a questionnaire.

The results are:

  • Pupils and teachers show an increasing awareness of noise.
  • Almost all pupils have a positive attitude towards the use of Audiovisual Noise Indicators.
  • The teaching atmosphere is consistently sensed more enjoyably.
  • The majority of pupils and teachers regard the Audiovisual Noise Indicator as independent observer, who points to the noise.
  • Most of the schools want to continue the use Audiovisual Noise Indicators.
  • Vocal overstressing of the teachers is declining.
  • The use and the periods of use depend on the work phase.
  • Many heads of school are demanding to take the Audiovisual Noise Indicator into the standard equipment of a school.

After 6 month of field-testing, the use of Audiovisual Noise Indicators has proven its value.

Further investigations will show, if the pupils school achievements improve with the use of Audiovisual Noise Indicators.
