Sound deadening, anyone use acoustic panels?

I was getting a hearing test done last week and went into this "acoustic booth".

It's insane how quiet it is in there.

I think it blocks out high frequency noise specifically.

I've read reducing decibels is different, use of heavy curtains etc., increasing sound absorption with furniture and throw cushions etc.

In any case, anyone ever used those acoustic foam panels to deaden sound?

.....

There's this vid of a dude using them on the back of his fridge to dull the refrigeration humming,

I did the above with my fridge today (live in studio so sleep is same room as fridge).

Seems to get kind of hot around the back.

Hope that foam doesn't catch on fire.

I ensured not to place it beside the compressor, but some of it touches the coils on the back panel.

Your fridge needs good clear air circulation to function at the back, do not restrict it.

Fire hazard from a fridge is quite high. This fire in London tower in 2018 started from a fridge. But there are fire resistant foams available, so I would rather go in this direction.

Acoustic panels will not block sound coming in or out of the room. They'll only reduce echo within the room.

Is this cool.... ?

Esel

Not cool. Think crazy - and dangerous.

Oh my God, get that stuff out of there!

lol yes, cheers for the heads up.

Noticed the motor was running overtime after a couple hours.

Coils were super hot.

Got the material out but now I'm back to sleeping in the same room as a noisy fridge.

Is that a counter top free standing mini fridge?

Can you not just move it to another room & use it as required.

You could place these panels, if you already have them, flat on the wall behind the fridge and cover the area bigger than a fridge and place the fridge in a few cm distance for this foam to let air circulate. But it would only slightly reduce the sound.

Kind of a pain when making dinner though, no?

Emma2019

You could put the fridge on a timer plug to go off for an hour or two as you're going asleep, once you dont open the door it should be ok I'd think.

If its bothering you during the day white or brown noise playing could help ignore it (brown noise is deeper and nicer imo).

I think I'd rather the mild inconvenience of having the fridge in a different room while making dinner than having to listen to it while sleeping.

Have you tried sleeping in the bedroom recently? With earplugs even?

Check the temperature in the fridge. If its set too cold it'll make more noise and eat more electricity.

A fridge is a heat pump, the coils at the back have to be warmer than their surroundings to dump heat so never cover or restrict airflow.

Make sure fridge is level and put something under the feet to isolate sound.

The worst sound is the refrigerant moving through the coils at the back.

The compressor itself isn't invasive, just that horribly fluid-through-coil din.

Got woken three times last night, each time to that horrible compressor and sound of hydraulic refrigerant.

So this morning I moved the fridge into what used to be the bedroom.

I can't believe I have to go 2 rooms over to get milk for my oatmeal, but wow, the peace is good now.

Living in a studio, having to sleep beside the fridge for years, damn that must be horrible.

In this weather and assuming normal room temperature, milk can be left outside the fridge for a few hours, without going sour. Just put as much as you will need in a jug and cover with a net cloth.
