White noise for a rattling AC
White and pink noise that covers AC hum and clicking.
40%
An AC or compressor hum is a steady tone your brain gets stuck on, and clicks wake you. Broadband noise hides the tone and blurs the clicks.
This preset uses more white and pink noise than usual, because hums also reach higher frequencies.
A new or loud rattle can mean a fault – it's worth having a technician check it.
