Something that makes u hear from ur own ears
Most likely the room has some sort of motion sensor to tell if someone is present. A heat sensor can tell if a person is in the room by the heat generated by the human body. A sound sensor can respond to noise made by a person walking, talking or otherwise. Either will work. The triggered sensor can turn on the lights or anything else electrically. The lights are usually attached to some kind of timer so that if no activity is detected in the room for a while, the lights are turned off until the next time the sensor is triggered.
operational definition of terms
Yes, it is an instrument for recording. A microphone is a sensor device that converts mechanical pressure waves or sound in air into electrical voltage waves. Speaking into a microphone excites (moves) a diaphragm that is coupled to a device that creates an electrical voltage proportional to the produced sound pressure.
Sound configuration is the setup of your sound card, volume, and speaker arrangement.
No. There is really no one material that is sound proof. Many materials can reduce sound levels, but reducing sound is not what you might think of when you hear sound proof.
Something that senses light, movement or sound
how sound sensor work
This term is often used with electronics and engineering. By definition, the recovery time of a sensor is the time a sensor takes to return to a baseline value after an event.
The sound sensor provides an output signal voltage that responds to sound detected by a microphone. It will only respond to loud sounds.
Actually, there is a sound sensor. It is built in to the NXT Intelligent Brick.
Relating to sound or sound waves.
There is the main robotics brick, four wheels, two balls, ultrasonic sound sensor, touch sensor, light sensor, sound sensor, cables, and many other bricks
They are mainly used in various different kinds of Microphones. Sound sensor is also used in mobile phones.
The definition for knell is the sound made by a bell. It typically describes the sound of a bell that is rung for a funeral or death.
