This cardioid microphone, with its main axis along its side, improves speech intelligibility in very loud environments. It is designed for the very closest speech pickup, i.e. directly in front of the speaker’s mouth. Its low-frequency rolloff is compensated by proximity effect. Thus it has (up to the point of its high-frequency emphasis) a flat frequency response for the speaker’s voice, while showing a rolloff at low frequencies for all sound that originates from a greater distance. As a result, background sounds are picked up less strongly than the person speaking.
– cardioid for lateral pickup – for pick up of speech or music at close range (under 10 cm) – considerable attenuation of low frequencies
