什么是EN50332測試?
隨著科技的發(fā)展,科技給人民生活帶來了便利,也有些電子產(chǎn)品會產(chǎn)生產(chǎn)一些噪音、輻射的危害。如何限制這種危害呢?就產(chǎn)生一系列的法規(guī),比如長時間、大音量的收聽音樂對會耳朵造成傷害,EN50332就是為了防止這一傷害,EN50332規(guī)定了便攜式播放設(shè)備的聲壓、輸出電壓、音頻穩(wěn)定的測試。測試范圍包括:所有帶耳機插口的便攜式音響設(shè)備和單獨的耳機產(chǎn)品都需要做EN50332測試,也叫聲壓測試,有些客戶也叫SPL TEST。
EN50332的測試有哪些?
EN50332分為兩個部分,分別為EN 50332-1和EN 50332-2,其中:
EN 50332-1:2013 Sound system equipment: Headphones and earphones associated with personal music players - Maximum sound pressure level measurement methodology - Part 1: General method for "one package equipment" 音響系統(tǒng)設(shè)備:與便攜音響設(shè)備相應(yīng)的耳機和頭戴式耳機.最大聲音壓力水平測量方法和限制考慮.第1部分:單一包裝設(shè)備的一般方法
EN 50332-2:2013 Sound system equipment: Headphones and earphones associated with personal music players - Maximum sound pressure level measurement methodology - Part 2: Matching of sets with headphones if either or both are offered separately, or are offered as one package equipment but with standardised connectors between the two allowing to combine components of different manufacturers or different design音響系統(tǒng)設(shè)備:與便攜音頻設(shè)備相應(yīng)的耳機和頭戴式耳機.最大聲壓級測量方法和限制考慮.第2部分:單獨提供或同時提供時頭戴式耳機設(shè)置的匹配
