    Room Treatment

    Cheers! It’s been a labour of love; very educational and strangely enjoyable. I’m still chasing some minor improvements... but the diminishing returns are now so steep that it’s becoming difficult to measure let alone hear the benefits. That’s what I like about acoustic treatment: there’s an end point in that you either run out of money or space! It’s a finite form of GAS Good points above about sound proofing vis-a-vis treatment. I haven’t attempted a soundproofing project myself so can’t comment from experience, but I know it’s an endeavour that doesn’t reward half measures. @charic don’t let that put you off though mate! If you’re a handy DIY-er then you can make a very decent job of it with sufficient elbow grease (and budget). If you’re interested I highly recommend this book: Home Recording Studio: Build It Like the Pros Quite technical in places, but nothing you can’t get your head around! Covers everything you need to know about building a home studio from scratch. The author, Rob Gervais, is also quite active on gearslutz.com and commonly responds to questions. I found it overkill for my purposes - mine wasn’t a build project as I wasn’t aiming for soundproofing, but it was a good read nonetheless. If I can find my copy you’re welcome to have it... I’ll have a root around the bookshelf and see if it turns up.

    Venue v Practice Room

    Small rooms by their very nature nearly always have terrible acoustics, that’s a fact. Gig venues are generally larger and thus less susceptible to some of the worst issues; but they can still sound crap. Acoustics are reliably unforgiving at the best of times. PS: The idea of a drummer going full tilt in a room the size of a domestic garage is plain crazy to me. Makes my tinnitus go wild just thinking about it. Some of you guys must have thoroughly trashed hearing. I SAID SOME OF YOU GUYS MUST HAVE... oh never mind 🙄

    Room Treatment

    PS: photos or a rough sketch of the room with measurements would be useful.

    Room Treatment

    REW results! Excellent. Now we can get to work... Email the REW .mdat file to me here and I’ll take a proper look at it for you: [email protected] You ideally need to measure left speaker on its own; right speaker on its own; and then both speakers together (but not a big problem if you haven’t done so). At first glance your frequency response looks very typical of a small room; no concerns there other than the big dip in the high end which is unusual. I’d need to adjust the view on your waterfall graph as it’s currently just showing a load of ‘noise floor’ (background hum in the room) which is masking a more clear interpretation of the results. I can also check the impulse response for any significant reflections (again hard to tell from the view you have above). Email over the file and I’ll post some thoughts here, along with some new graphs 👍

    Room Treatment

    You're welcome! This is one of the best introductions to REW and acoustic measurements that I've found. Follow the advice there and you won't go far wrong
  6. And I don't think you can mention soul without this modern-day classic...

    Peaks most likely yes; dips most likely no

    Room Treatment

    Hi Pete, Firstly, it's "not too bad"! It looks like a typical untreated room and I've seen a lot worse. Sonarworks is a great tool for room EQ; but a poor one for actually measuring room acoustics. I assume you must have a measurement microphone? If so, download a copy of Room EQ Wizard (for free) and use that instead - it's a different league and you'll get a much clearer picture of how your room is behaving. That said, from the Sonarworks image you've posted I can suggest that: The low frequency dip around 80hz is very common, to the extent that literally every small room will show a similar dip (usually somewhere between 60-100Hz). It's caused by a standing wave (aka a 'room mode') and/or what's known as SBIR (surface boundary interference response). Likely a combination of both. Try pushing your speakers right up against the front wall - literally within a few millimeters, which should help to lessen it a bit. Beyond that you need install acoustic treatment, especially on the rear wall. 60cm depth of fluffy insulation (same as what's in your loft) is ideal. The peak at around 160Hz is likely caused my another room mode, this time resulting in a peak rather than a cancellation (here's a handy tool for working out the modes that are present in your room). Sonarworks should be able to get that under control to a large extent. What looks like another cancellation dip around 300Hz (i.e. caused by sound reflecting off walls/ceiling). Things then get a bit weird in the high end! The peak at 8Khz, followed by the dip around 12kHz, are also likely to be boundary reflection/cancellation problems (aka comb filtering), but it's unusual to see such a large dip in the higher frequencies. Possibly something to do with the shape of the room itself. Carpet will do very little to reduce reverb time (other than in the high frequencies). What you're not seeing here are the decay times, which are arguably just as - if not more - important than the frequency response, especially in the low end (where long decay times are notorious for causing 'frequency masking' - i.e. making it difficult to discern between different bass notes). Get REW hooked up, as you mention, and give it a shot with that instead. Unless you're able to clap at 50Hz...
  9. The only time I ever visit a music shop is when I need something immediately that day and am too impatient to wait for an online delivery (a set of strings or a patch cable, for instance). I’d love to say I’m more supportive of music shops, but I just find it far more convenient to shop online. Although I appreciate that’s perhaps not a popular opinion I just can’t be doing with the faff of: Actually visiting them. Finding out they don’t stock what I need when I do visit (despite it being shown as available on their website). Discovering that I could have bought the same item cheaper online anyway. Human interaction generally. I can see the value if you want to try out an instrument before you buy it. And I'm all for shops offering a more independent alternative to faceless globalism, etc. But meh.

    EBay cash conundrum

    Aye it's an interesting part of the country and somewhere I'm familiar with. You have Clitheroe (or Clit Hero as I refer to it), which used to have (and perhaps still does) the "highest concentration of millionnaires-per-square-mile in the UK outside of London". And in stark contrast you towns like Nelson that suffer from severe levels of socio-economic deprivation.

    Room Treatment

    Yep, I would certainly vouch for Sonarworks (having used it myself) and also Dirac Live (which I use now). The latter gets a better grip on the low end in my experience; at least that's what I observed from acoustic measurements taken in my own room. Room EQ software does nothing to fix boundary reflection nulls and slow decay time problems, as you mention. But it's great for reducing peaks and allowing you to control the overall shape or 'house curve' of your room's frequency response, in ways that are difficult to achieve with acoustic treatment alone. Some pro studios also use Trinnov, but you need around £4K to burn for that. I'd normally recommend EQ software as the 'icing on the cake' - something to use once your room acoustic treatment is otherwise finished. But if circumstances dictate that it's the only option available then sure, go for it! 👍

    Room Treatment

    In case anyone finds this useful... slim chance, but you never know!... here's a link to a whole bunch of acoustic measurements from different rooms, which I compiled over on the Gearslutz forum: https://www.dropbox.com/s/bt7xvsok7w3r4u6/Gearslutz.mdat?dl=0 It allows you to view and compare what the acoustics of different people's rooms 'look like'. Each measurement contains notes on the size and volume of the room, plus a link to the relevant thread on gearslutz.com where you can read up on the methods of acoustic treatment used. You'll need a copy of Room EQ Wizard software to open the file, which is free to download from here: https://www.roomeqwizard.com Maybe useful to anyone who's planning to improve the acoustics of their room and wants to get an idea of what the end result might look (or more importantly sound!) like.

    Lets talk about Musicman

    For me it’s: That tone, which cuts through the mix like a buzzsaw Great build quality Optimum string spacing and playability (personal preference of course) I love Fender too. But with the StingRay, Leo and company got it spot on.
