Hey All,
There's this ultrasonic motion detector in my room that the studio installed. Which is great at turning off my lights if I forget to and also great at ruining any chance of pitching the recordings I do in the room. It's blazing at about 30+khz so when I slow down anything I record in here the cue is useless(devoured by 15k frequencies). The unit hardwired into the ceiling so I can't turn it off and I tried putting a moving blanket of the the device but that doesn't seem block any of the high frequencies. Any ideas? Can any type of sound proofing fix this?
