客戶要我提供符合EN50332-3的證書,這個標準有沒有?測試的結果是證書,還是報告呢?聲壓測試只對耳機,還是喇叭輸出也要測量?到底是要求輸出低于100DB,還是低于150MV?那位DX知道的請賜教.謝謝!
the evaluation is :
for EUT with headphone, the MAX sound pressure level is less than 100dB.the equipment continous A-weighted sound pressure level is les than 90dB.
for headphone ,the input voltage is larger than 75mV when SPL of headphone reach 94dB,
for player without headphone, the Vm is less than 150mV,and the Vm shall be showed on the label.
