    Sound Activated Switch

    A sound activated switch can turn on a light,or small appliance with any sudden loud sound or act as a broken glass sensor for an alarm system. So simple to use. Just Clap on - Clap off!

    With voice recognition now easily feasible, voice activated switch operations can be of help. Sound operated switch can easily get activated or deactivated with noise sources - particularly from high frequency sounds and low frequency vibrations that can travel through earth. Simple sound activated circuits if have large time constant in noise filter then perhaps can reduce effect of noise. Dr. Shyam Sunder Tiwari
