Questions and Answers for Paintable White Fabric Circle 24 in. Sound Absorbing Acoustic Panels (2-Pack)

A:  no, fiberglass insulation doesn't absorb sound very well below 600 hz, about mid-range on a piano, so a low hum won't be fixed with these. build a box or enclosure around the transformer containing fiberglass insulation 6-8" thick, that would do it.

A:  No, these are designed to absorb sound reflecting off hard surfaces within a room; they do not increase sound blocking from adjacent rooms. A common way to reduce noise from a neighbor is to increase wall mass by adding a layer of drywall and decoupling.

A:  to really block sound you could add a layer of insulation and then another 'faux' wall of drywall, or just some packing blankets and a 'faux' wall of 1.5" insulation pink board over that painted white for an easy redneck fix.

A:  spray the panels with vinegar and dust with baking soda. the chemical reaction should soak into the top layer of the fiber and neutralize the urea and bubble it out to the surface, then towel off dry.

A:  Buy some cats.

A:  totally could use these in a mobile home on a wall. they're pretty light. p.s. they absorb sound better if you mount them 1" off the wall
