        Microphones are the most common audio devices, and selecting the right one can be complex for non-professionals due to various parameters. If we need to choose a microphone without fully understanding the product, how should we proceed? Generally, evaluating a microphone involves looking at the following key parameters: Sensitivity Microphone sensitivity has its own measurement standards and relatively complex formulas, which we won’t delve into here. However, it’s essential to remember these points about sensitivity: Does higher sensitivity always mean better sound? Yes, but not entirely. Higher sensitivity also means more noise is captured, so we need another parameter\u2014Signal-to-Noise Ratio (SNR)\u2014to assess microphone quality. Signal-to-Noise Ratio (SNR) SNR can be […]<\/p>\n","protected":false},"author":1,"featured_media":1962,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[400],"tags":[634,632,633],"class_list":["post-1960","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-product-guides","tag-component-selection","tag-parameter-tradeoff","tag-spec-benchmarking"],"_links":{"self":[{"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/posts\/1960","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/comments?post=1960"}],"version-history":[{"count":0,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/posts\/1960\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/media\/1962"}],"wp:attachment":[{"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/media?parent=1960"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/categories?post=1960"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/tags?post=1960"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
