Computer-based tools for testing hearing, speech and vision

• Aim: organising mass screening tests which results should demonstrate occurrence of impairments of communication senses in children and in general public

• Idea: application of modern computer-based tools for testing hearing, speech and vision and a systemic solution for mass screening examinations using state-of-the-art telecommunications and information technologies.

Launched on December 12, 1999 the System of Common Hearing Tests "I can hear " was thefirst result of the conceptual and programming work.Following a successful completion of pilottests, the system "I can hear" was made commonly available in two forms: as an Internet

application accessible at: www.telewelfare.com and as a software on CD-ROMs.Subsequently, Internet systems for testing speech & vision were engineered and launched.

PC-BASED NOISE TESTER is a multimedia computer system designed for testing environmental noise with the use of personal computers. It is particularly useful and effective for fast checking whether the level of noise exceeds norms in: urban areas, roads and railroads, at the airport surroundings, in workshops or factories and in private living places.
