acoustics

Hi, I want to make 4 DIY acoustic panels. I've read on reddit that the important thing is the thickness of the material, not have to worry about material type itself. But I have no experience, what should i choose? I like that polyester thing or rockwool 'cause of the thickness they provide...

Hello! First post, been enjoying reading this forum and the Floyd Toole book, good fun. Planning the setup for the living room I'm soon to move into. Wondering if you all can help decide between Genelec and Revel.... or something else! Floor plan is below. -There's a wall with a window...

Hello everyone and thank you in advance for sharing your reflexions on this topic. The purpose of this thread is purely on acoustic treatment of a room and more specifically how or what to change from a traditional studio design (without in-wall speakers) to a studio using Kii's. I would like...

Room is almost a square (9x11 feet), with one side being a long doorway opening, to a larger room, therefore no right wall really. Right wall 5.5 feet away from Mic, with 3 windows. Mic is almost positioned in the middle of the room. There is pretty much no left wall as you can see. All graphs...

I'm planning to build some bass traps. The rear wall will be treated with about 40cm of glass wool but I want something more attractive for the front wall. I really like the looks of triangular bass traps; they're not as visually intrusive as square bass traps to me. I do all my caculation...

Hi all, Helmholtz resonators are enticing for the control of low frequency room modes, and it's remarkable that such small structures can resonate at such low frequencies. However, they seem to have been largely written off by the audio community because they so often fail to perform as...

Hi all! I want to share this application to calculate and evaluate the natural frequencies of rooms modeled in 3D. At the moment, the application does not consider materials, only rigid surfaces, but it is a very useful tool to evaluate the eigenmodes in irregular rooms. It is recommended to...

Hello, I was wondering where would I place the panel on the celling, it is a slanted celling which goes (Short to High). How would I calculate the first reflection point, my guess would be between the centre of the listening position and the speakers. Also would the panel be Vertical or...

Hello, I am new when it comes the room acoustics, I have been mixing in headphones most of the time, and now I would like to start mixing on speakers , I have set up my speakers and my best listening position in my room, it is a small room with a slanted roof. I have ran some test on REW with L...

Hi folks, I have a question about acoustics for you. Yesterday I attended a meeting with other kid's parents in a school canteen (cafeteria in USA? ). I took a picture of the ceiling: I'm assuming they have an acoustic purpose from now on. It seems a low density foam of about 4 cm thick...

I'm in contact with a company who produces panels made from PET (Polyethylene Terephthalate, not domesticated animals). They send me their performance data for a 15mm (0.59 inch) thick panel… Does the low frequency absorption seem unusually high to you too or am I misreading it?

Hi everyone, I am trying to set up Neumann KH80 for mixing practice and as you can see, my room is super tiny. The dimensions are 280cm x 250 x 240 (L x W x H) and that would be 9.18ft x 8.2 x 7.8 for my American friends. I used Behringer ECM8000 and played sine sweep playing through both...

Hi everyone, I'm trying to mix my songs in my tiny bedroom. Is mixing with monitor speakers a viable option in this room? Sorry for the bad drawing, but here are the approximate measurements of my room: L: 280cm (110") W: 250cm (98.4") H: 240cm (94"). I typed the measurements into Bob Gold's...

I'm not sure the following is even possible due to how high-frequency sound is perceived in off-axis listening configurations. In any case, here are the 'concept parameters': hardware/audio optical or coax digital input single speaker configuration available (maybe something like a sonos play...

Hi all! I'm so glad I found this site. It combines two of my favourite things: audio and science. When I was shopping for my first studio monitors four years ago, I didn't know much about the subject except that I had read they were supposed to be accurate and have a flat frequency response. I...

Hello to all, Passionate about music and acoustician, I manage a website about acoustics and hi-fi. I think that it will be able to please some people, especially the "blog" section. Here is the link : https://www.pytaudio.com/en/ Looking forward to discuss with you :) Musically

As the title states this is my first foray into taking actual room measurements. I'm a firm believer in room acoustics, speaker and listener positioning, distances from walls and speaker boundary interfaces. I'm using a UMIK-1 ver2 on a boom stand. USB into my HP Envy Tower --> USB RME ADI-2...

Any recommendations for speakers that play nice close to the wall?

Roughly sorted according to theme, and chosen because I think they're worth listening to. The difficulty ranges from introductory to real heavy. Part of the way I dive into a topic is to find lectures by knowledgeable people and then build archives. So maybe others will find this useful as...

I posted on a couple of other forums. i haven't had much luck. I realize this post is very specific & complex. But i can't figure out on my own what my mistake is. Hoping someone here will be able to help me out. Using this post as a reference, I tried an experiment. I connected a Extech...
