The bottom 8 is typically handled well by the various furnishings within a room. While there are 20 corners within a room, you really only need to treat the side 4, and the top 8.

As with the Acoustic foam tiles above, I strongly suggest reviewing that video to ensure minimal damage is done to these upon the need to remove them. This is strictly related to the physics of sound because longer wavelengths are barely affected by velocity based dampening. The thicker the that this acoustic wedge is, the lower frequency that it will be able to effectively absorb. The Answer: 20! Advertisements My recommended bass traps for streamers It helps a fair bit to limit the amount of vibration that is transferred to the wall.Īnyways, I’m a bit off topic now, back to the bass-ics… AdvertisementsĪ quick piece of Trivia: How many corners are in a square or rectangular room? I’ll give you a hint, it isn’t 4! If you happen to suffer from this issue, and can’t go live without the AC on, consider getting a strip of foam to put the AC on. While these are mostly optional, they do make a significant difference in improving the audio of a particular room, particularly if you have a window-mounted AC like I do (this exact model) that transfers its vibrations to your wall and turns it into a low-frequency amplifier. They typically come in a triangular wedge shape, and they are designed to combat low-frequency rumble within a room. The frequency range of 60-300 is affected by bass trapsīass traps are a special kind of acoustic dampener that is placed in the corners of a room. If you’d like a more in-depth coverage on the subject of sound treatment, check out this article I wrote awhile back that goes into the thick of it. That isn’t to say that the thin stuff does nothing, I’m merely saying that it simply isn’t worth buying when the thicker stuff is available at a comparable price. The story begins to change its tune at 2 inches and beyond, where the mass of the foam and the thickness within have a chance to actually do its job. While it is leagues better than the 0.4 inches thick foam, it is still not worth your hard-earned money.

If there is one thing I want you to take away from this article, it is this…Įven 1.5 inches misses the mark. There is simply not enough mass to have any real effect on the sound outside of the highs and high-mids. It is laughable and insulting to find foam that is 0.4 inches thick, being sold as acoustic foam. I’ll say this right now, any foam you buy that is less than 2 inches thick is not worth considering. The first, and cheapest option to reduce room echo is to slap some Acoustic foam on the walls of your recording environment. If you are attempting to achieve acoustic isolation, Please consult an Architectural Acoustician who can safely implement isolation.Įnsure you follow this pattern of rotating panels. Whether they consciously acknowledge it or not, you will scare people off if your content can’t offset the negative factor of echo. It’s a subtle annoyance, ever-present for the entire duration of your stream. But treating your room for echo and reverb goes a long way to preventing your audience from getting annoyed. With that being said, for a live streamer, you don’t really need to worry about achieving acoustic isolation. If you like breathing as much as I do, I hope you heed this warning. In other words, you’ll suffocate yourself from carbon dioxide buildup as you breathe all of the oxygen away. What I am referring to is that certain methods used to achieve it will cut off air circulation to a room in favor of isolating a room from external sound. In other words, it’s just marketing lingo.Īchieving Acoustic Isolation is extremely difficult, expensive, and if you don’t know what you’re doing, even dangerous to you. If you see “Soundproofing” being advertised on any acoustic material, know that they are targeting a blanket keyword that people use who are unfamiliar with sound dampening and acoustic absorption. I’ll quickly mention that reducing echo or reverb in a room shouldn’t be confused with soundproofing, which has a more specific term that is better suited to categorize it Acoustic Isolation. Within this article, I’ll be covering a range of acoustic absorption materials used to combat this phenomenon. Of course, this is depending on what your definition of expensive actually is. Luckily, this problem is one that has a somewhat simple, albeit potentially expensive solution. In fact, tens of thousands of creators on YouTube and Twitch are plagued by it. Got a problem with echo on your stream setup that is bugging the ever-living heck out of you? You’re not alone.
