Array microphones are used in situations where concurrent measurements are required at several points. For example in the analyses of:
They are also of particular value when measurement opportunities are few and far between either because of costs or repeatability. |

;) ;) The Array Microphone Types 40PH and 40PL are low-cost microphones for general-purpose measurements in arrays and matrices. They have a wide useful frequency range reaching up to and a large dynamic range topping at around 134 dB. They have an integrated CCP* preamplifier and built-in TEDS** enabling them to be programmed as a complete unit. Their manin difference lies in the sensivity: the Array Microphone Type 40PH has a sensitivity of 50 mV/Pa as opposed to the Type 40PL, which has a sensitivity of 10 mV/Pa. * Constant Current.Power Supply |
