Excessive noise is harmful to hearing. The Safe Sound Indicator helps children learn the importance of
protecting their hearing and gives teachers a tool to keep the noise levels down.
The SSI was developed by The National Foundation for the Deaf, a New Zealand non-government not-for-profit that works with its member organisations to
• support people who are deaf or hearing impaired
• encourage hearing preservation
• promote good sound.
Good Soundz Ltd (GSL) was established by The National Foundation for the Deaf
to market its products.
NFD and GSL are registered with the New Zealand Charities Commission. Registration numbers: NFD - CC10300, GSL - CC46041
