Ich habe ausgenommen, wie ich einen lichtschalter betätigt habe. Man kann das geräusch für das an- und ausschalten verwenden. I have excluded how i operated a light switch. You can use the sound to turn it on and off.
There are very old fluorecent lights in our garage and i recorded one of them. The hum was very quiet, so i made that louder in audacity and removed background noise which was also amplified.
The whole precedure: switch-on-klick. Heats up. Hisses with a few nice whistling melodies (from 00:27 on). Boils. Automatic switch off. Close stereo recording (10cm) with sony pcm-10. Pretty low background noise (kitchen ambience).
Raw binaural recording of a creaking floor, a radio with static being turned on and off, and a light switch being flicked. Best heard using earphones. Recorded using roland cs-10em with a sony icd-px470. Feel free to let me know what you do with the sound. :).
Fluorescent light is turned on, it flickers for a moment trying to strike then that wonderful fluorescent hum. There is also some scary electrical noises when the switch is flipped. Recorded on a sound canvas 702 with preamp with akg c414b microphone.
The wonderful sounds of a 1981 ibm pc model 5150 being turned on, the 5. 25" disk drive checking if a diskette is inserted, the pc emitting its idle hum, and finally being turned back off.
