I need background noise when I work and I often use a small TV in my study, either playing DVDs of old TV shows or tuned to a nostalgia channel. I don't want sound to be too loud, though.
I recently bought a 7" TV that I can easily tuck out of the way, so I can still see the images once in a while, like I prefer, but it doesn't take up much space anywhere. The only problem is that, for some videos and some channels, the minimum volume is still rather loud. There's one channel I can have on that, with the volume set to 1, I can hear in surrounding rooms with the doors closed.
The speaker is on the back of the TV and is about 2" tall by 1" to 1.5" wide. I used duct tape to tape some heavy cardboard over the speaker. That helped, but not by much. I can touch a spot, over the speaker, where I can press on the duct tape and cardboard just a little and it significantly muffles the sound. I broke off about 2" off the end of two pencils and taped them down over the duct tape and cardboard covering, in hopes the stiffer pencils might hold down vibration, but it doesn't help much.
I've thought of trying to tape over something padded or a quilted fabric, but I don't have anything I can cut up.
What could I easily put together or use to tape over the speaker grill on the back of this small TV that would do a good job of muffling the speaker sound without fuzzing or distorting the sound?
