Abstract:Low-cost electret microphones are ubiquitous in telecommunications equipment. They are capable of providing nearly ideal response, while often employed as point receivers. However, uniform response is not always optimal, especially for digital applications or microphone arrays, nor is it easily achievable given mechanical packaging constraints. It is therefore essential for a given design to incorporate frequency-dependent effects of the microphone housing. Frequency shaping is typically done electrically, but… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
