Abstract
A method and apparatus are provided for warning when the amplitude of conversations exceeds certain values. The apparatus includes a microphone and related circuitry which continuously produce a signal related to the amplitude of the conversation while the apparatus is operational. A comparator continuously compares the signal to a pre-set first value and produces an output as long as the signal indicates that the conversation exceeds a certain amplitude. There is a discriminator responsive to the comparator output which provides a discriminator output when the duration of the comparator output exceeds a pre-determined value. The discriminator is connected to an alarm which produces a warning signal when the discriminator provides the discriminator output. There may also be a second comparator which produces a visual signal when the amplitude of the conversation is above an amplitude which may be below the amplitude which activates the alarm.
