Carpal Tunnel Syndrome Symptoms & Signs. Carpal tunnel syndrome arises from compression of the median nerve that supplies the hand. Symptoms begin with numbness and/or tingling of the hand in the distribution of this nerve (the thumb, index, middle, and thumb side of the ring fingers).
An Condenser microphone is a type of microphone that consists of a pair of charged plates that can be forced closer or further apart by variations in pressure. In effect, the plates act like a sound-sensitive capacitor.
In a condenser microphone, the diaphragm is mounted close to, but not touching, a rigid backplate. (The plate may or may not have holes in it.) A battery is connected to both pieces of metal, which produces an electrical potential, or charge, between them.
