- Improve acoustics within your home theater
If you live in a multi-dwelling building, it is likely that your neighbors complain when you blast your stereo or favorite movie. Not only will you appease your neighbors by properly soundproofing your home theater, it is also easy to make your audio system sound as if it cost two times its actual cost.
Before I tell you the proper soundproofing techniques, you must first understand a few principles of acoustics and soundproofing. For your home theater, you must understand Sound Transmission Class (STC) to determine what you desire for your home. In short, STC is the average decibels (dB) lost through a barrier across the range of frequencies 125 Hz to 4000 Hz. A high-end home theater will typically produce sounds as loud as 100 dB to 110 dB. To compare this, a quiet room typically hovers around 40 dB. To properly balance this, the wall between the two rooms would require an STC rating of 60.
Typically, an interior wall composed of stud construction with drywall on both sides has an STC rating of 30 to 34. If the separating wall were to remain non-soundproofed, the dB in the room adjacent "quiet room" would increase to 70 dB (100 – 30 = 70). Considering that a loud home theater, at 100 dB is too loud to hold a conversation, the adjacent room at 70 dB would be too loud to hold a conversation.
One common misconception in soundproofing is that filling the wall with egg cartons will reduce noise transmissions between rooms. In actuality, test results have shown that filling your wall with egg cartons will not produce any measurable reduction in sound transmission between rooms.
To achieve the best results, you should use the proper combination of soundproofing and acoustic materials such as our QUIET BARRIER® HD for soundproofing and SOFT SOUND® Home Theater Products for improving acoustics.
