The so-called rub and buzz refers to the annoying noises generated when testing a loudspeaker with a swept signal, which are caused by system nonlinearities. Most of the noises are caused by manufacturing defects in the loudspeaker, such as loose diaphragms, loose coils, non-centered diaphragms, rubbing of coils, air leaks, or other defects. These defects cause short impulses with sudden changes in transient energy, resulting in ear-splitting noises. Trained listeners can effectively distinguish the noises, but it is labor intensive and hearing fatigue reduces the accuracy of the test, making it unsuitable for product testing on production lines.<\/p>","protected":false},"excerpt":{"rendered":"<div class=\"e_richText-58 s_title clearfix response-transition\">ZCLK-001A Acoustic Laser Analyzer can test the performance parameters of electro-acoustic products including frequency response curve, impedance curve, harmonic distortion, intermodulation distortion, heterodyne test and so on.<\/div>\n<div class=\"e_container-19 s_layout response-transition\">\n<div class=\"cbox-19-0 p_item\"><\/div>\n<\/div>","protected":false},"featured_media":5637,"comment_status":"open","ping_status":"closed","template":"","meta":{"themepark_post_bcolor":"#f5f5f5","themepark_post_width":"1022px","themepark_post_img":"","themepark_post_img_po":"left","themepark_post_img_re":false,"themepark_post_img_cover":false,"themepark_post_img_fixed":false,"themepark_post_hide_title":false,"themepark_post_main_b":"","themepark_post_main_p":100,"themepark_paddingblock":false},"product_brand":[3538],"product_cat":[2020,52],"product_tag":[2032],"class_list":{"0":"post-4250","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-zctek","7":"product_cat-electroacoustic-device-testing-equipment","8":"product_cat-tydzcs","9":"product_tag-2032","11":"first","12":"instock","13":"shipping-taxable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product\/4250","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/comments?post=4250"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/media\/5637"}],"wp:attachment":[{"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/media?parent=4250"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_brand?post=4250"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_cat?post=4250"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/ad.wbyq.cn\/en\/wp-json\/wp\/v2\/product_tag?post=4250"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
