Human ears have a unique physical structure that affects the perception of sound signals.  In order to evaluate the performance of dynamic receivers close to the real application conditions, the International Telecommunication Union (ITU) has defined special types of ear couplers (also called artificial ears) which can simulate the key acoustic attributes of human ears. … Continue reading “Testing Dynamic Receivers with Ear Couplers”

A dynamic receiver is an acoustic transducer and while it shares many of the same electroacoustic parameters and subcomponents as the loudspeaker driver there are also some differences. But first let’s mention some of the similarities. By way of construction, both the dynamic receiver and the loudspeaker driver have a motor structure comprising of a … Continue reading “Dynamic Receiver: How does it compare with an active loudspeaker driver?”

Microphones can be classified both according to transducer principle and by directivity or polar pattern.  Transducer principle is the method of converting one form of energy to another. Since we have already covered transducer principle of an electret condenser microphone (ECM) in a previous blog article , we shall focus on types of electret condenser microphones … Continue reading “Types of Electret Condenser Microphones (ECM) by Polar Pattern”

Key parameters for Electret Condenser Microphone (ECM) There are several key parameters that are used to describe the characteristics of an Electret Condenser Microphone (ECM). Sensitivity: Since a Electret Condenser Microphone is a transducer that converts acoustic energy into electric energy, one of the most important characters is the conversion ratio, i.e. what is the … Continue reading “Key parameters for Electret Condenser Microphones (ECM)”
