    Help Needed: Detecting High-Pitched Whining from LED Bulbs – Best Mic & Setup?

    I’ll have to look into this :) building a chamber could be a fine side project once I have some glorious time

    Help Needed: Detecting High-Pitched Whining from LED Bulbs – Best Mic & Setup?

    Will do! I'd love to document it here if/when this project takes shape. I hadn't considered sending Earthworks an email haha I guess they'd be the ones to know! Thank you.

    Help Needed: Detecting High-Pitched Whining from LED Bulbs – Best Mic & Setup?

    Oh duh! Good idea. I'll check for industry testing standards and see if I can find anything there. Thank you for the idea. I was thinking of putting the mic inside of my integration sphere to cut down on exterior "noise", although I'm not sure just how much sound that blocks.

    Help Needed: Detecting High-Pitched Whining from LED Bulbs – Best Mic & Setup?

    Yeah, I'm not sure how common it is for LEDs to emit any kind of noise but apparently, it does happen. I never noticed it and I've tested well over 300 different kinds fairly extensively. Not sure if this project is work the time, effort, and money, but figured I'd see what it would take. Thank...

    Oh, that does look nice! Low noise seems like it would be an advantage for this type of work. I hadn't considered something like this.

    Help Needed: Detecting High-Pitched Whining from LED Bulbs – Best Mic & Setup?

    We do LED testing, see here, and have had more than a few people mention they wish we'd tested for audible whine, something I hadn't noticed or considered. So I thought to myself how hard can it be? Seems like the approach is a low-noise setup, just gotta figure out the whole software thing...

    Help Needed: Detecting High-Pitched Whining from LED Bulbs – Best Mic & Setup?

    Hi everyone, I'm working on a project to detect and document high-pitched whining sounds from LED light bulbs. These noises are subtle, and I want to ensure that I capture them accurately if/when they’re there. Audio science is not my area of expertise so I was hoping some of you kind folk...
