I have a noisy box of mains-fed electronics in a cupboard that I would like to soundproof. (It makes a faint but annoying buzzing noise, presumably the power supply). Any suggestions? The box is about
30x30x10cm. I was thinking about fitting a plasterboard or MDF box around it. Has anyone done anything similar and care to give some advice? An obvious concern is that sound and thermal insulation tend to go hand in hand, so overheating could be an issue.- posted
