Bass Traps

What is the purpose of Bass Traps?   The main purpose of the bass traps is to improve the response of the low frequency in a room by reducing peaks, raising nulls and reducing modal decay lines. Peaks and nulls always vary in level around the room. Therefore,...

Soundproofing

What is soundproofing?   Soundproofing, also known as sound blocking, basically refers to the insulating materials used to stop the sound to enter or leave the room. Soundproofing materials are in most of the cases solid and heavy. To be more precise, the action...

MEMS Microphones

What are MEMS Microphones?   Microelectromechanical systems microphones (also known as MEMS) can be described as one of the smallest types of microphones in the market. Their development led to very small microphones with really high performances. The MEMS...

Liquid Microphones

What is a Liquid Microphone?   A liquid microphone, also known as a water transmitter, is based on Ohm’s law that current in a wire varies inversely with the resistance of the circuit. The sound waves from a human voice cause a diaphragm to vibrate. This...

Crystal Microphones

  What is a Crystal Microphone?   The crystal microphone is the type most widely used in lower cost installations. It has relatively high output level and high impedance. A long cable will reduce the high output voltage available from a crystal microphone...

Cardioid Microphones

Cardioid Microphones are microphones primarily used for picking up sounds with high gain from the front and sides but poorly from the rear. Their name comes from the fact that their directional sound pick-up is roughly heart-shaped in nature. Cardioid microphones are...
