Electro-magnetic interference from a desktop computer, and an AT&T; cordless phone handset CL82301 when held near the internal Ferrite antenna on the back right of a 13-year-old boombox listening to the AM broadcast band. Recorded 2 years ago so I forget where I was listening. Recorded with Goldwave from line-in. You hear EMI from the computer at first, then I bring the phone on standby near the radio and you hear a series of nearly pure tones. The phone comes on and you hear a distorted dial tone. I move the phone away from the radio for a few seconds and you hear the computer again, then I bring the phone near and you hear a distorted busy signal. I disconnect and the phone continues sending to the base for a few seconds so you just hear a hum, then the idle tones are heard, then the computer noise as I remove the phone.<br/>AT&T帶電腦噪音的無線電話AM Radio.wav<br/>聲道:2<br/>類型:wav<br/>sequence-of-tones、desktop、computer、busy-signal、radio-interference、digital、dial-tone、buzz、tones、noise、glitch、beep、electro-magnetic、hum、interference、distorted、EMI、pulse、electronic、am-radio、EMF、cordless-phone<br/>序列的色調、桌面、電腦、忙碌信號、無線電干擾、數字、撥號音、蜂鳴器、音、噪聲、毛刺、嘟、電磁、哼、干擾、扭曲、一個微笑、脈衝、電子、上午無線電、EMF、無繩電話<br/>資料來源:freesound ( https://freesound.org )
