      When designing microphones, one crucial factor to consider is the Acoustic Overload Point (AOP), a metric that determines how much sound pressure a microphone can handle before distortion sets in. Understanding and optimizing AOP is essential for ensuring that microphones provide clear and distortion-free sound in both quiet and noisy environments. What is AOP? The Acoustic Overload Point (AOP) is the sound pressure level (SPL) at which a microphone starts to experience distortion. Typically, when the Total Harmonic Distortion (THD) exceeds 10%, the AOP is reached. Measured in dBSPL, it\u2019s a critical factor for maintaining audio clarity in noisy conditions. Microphones with a high AOP can capture louder sounds without […]<\/p>\n","protected":false},"author":1,"featured_media":2220,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[605,607,590],"class_list":["post-2215","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-technical-insights","tag-aop-1","tag-clipping-level","tag-linear-range"],"_links":{"self":[{"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/posts\/2215","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=2215"}],"version-history":[{"count":0,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/posts\/2215\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/media\/2220"}],"wp:attachment":[{"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/media?parent=2215"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/categories?post=2215"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ecmicrophones.com\/ja\/wp-json\/wp\/v2\/tags?post=2215"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
