Acoustics for Residential Apartments


There has been a fairly decent-looking spike in enquiries for apartment soundproofing, understandably – as more people are spending most of their time indoors. I fully empathize with folks who try to do their best and function amidst constant distraction – and not all of it is sound-related. WFH Women, take a bow right now. And all you males who help your wives WFH, take a bow too. <Imagine saying this the other way around. We’re so far away from […]

Acoustics for Auditorium Spaces


JANUARY 20, 2015 / ROOPAKRISHNAMURTHY / EDIT This type of space is apparently the bread and butter for most acousticians – with most non-acousticians being aware of the necessity of acoustical treatment in such spaces. Other spaces are work for us too, but usually only after some problem persists beyond the ‘experienced’ trials of the construction period. Auditoria also suffer from the fact that most are over-treated for music, but just about right for speech. Here are typical acoustical issues that these spaces face. […]

Acoustics of Lounges and Clubs – 2


Great. Now that we’ve largely taken care of soundproofing in the previous post, let’s look at what happens in the interiors. All Glass  Glass is something we can’t avoid these days, and the challenge is to ensure that the sound field in a room is sufficiently diffuse, despite perfect planar reflections from large panes of glass all around you. This poses trouble even for the mids and highs, let alone the LF.  How do you introduce time and phase shifts? How do […]

On Studying Acoustics


I’ve been often asked these questions by a host of people, and considering most of these conversations run into at least an hour if any justice is to be done, I thought writing down the basic information would be useful. This is by no means exhaustive, just a starting point. Scope of Acoustics  The most beautiful thing about acoustics is that it is a very multidisciplinary subject. There are fields coming together at all levels – pure math or pure […]

Discernment


Now this deserves a mention because of the variation that exists here.  I’ve met people who’ve have told me that they’ve never done acoustical treatment at any place they’ve worked in, and their systems have always sounded excellent, and that the software we acousticians use to validate our estimates is only cosmetic, and is only for reporting purposes. I have no issues with their fond opinion. I only have an issue with the notion that it could be an absolute ‘opinion’. […]

Festival Acoustics: Quick Tip


This part of the recommendations is always free of cost. With everyone gearing up for the festive season, I’m only too happy to provide the name of a brand of ear plugs that I’ve found better than most others. dB Safe. Made of washable rubber, available at most medical stores for under Rs. 100,  works better than all the inefficient, memory foam stuff doing the rounds these days. Sturdy, washable piece. Please note, I’m not being paid by dB Safe or anyone to do this. […]

Acoustics for Lounges and Clubs


I’ve recently had a chance to look at a few of these projects not six months into my freelancing, and there’s plenty to be said here. Pubs and lounges have integrated themselves into the lifestyles of Bangaloreans for over 10 years now, and plenty of people spend the best part of their weekends catching up with friends and family at such places. This post is for a broad spectrum of audience – aimed at giving general information to people to […]

Acoustics for Cinema Halls


The conventional movie theater is giving way to a huge mall, with plenty of retail outlets, and the top floors of such places are usually dedicated to a number of small halls replacing the conventional movie theater experience. The large theater had a very different acoustical characteristic and these small halls require a fairly different approach for acoustical treatment. I’ve worked on the PVR malls at Orion mall, and now at the Vega Mall, and some issues seem to be […]

Acoustics of Restaurants


Actually, there’s no single view to take on this topic. Restaurants are theme-based, these days, and ambiance of older restaurants become their “theme” after a period of time.  Let’s talk about a few ‘themes’, and then we’ll look at some common  acoustical issues at such places. Eerie Places I once  went into a restaurant called Gufha. The word means “cave”. True to its name, I walk into seemingly absolute darkness, one bright sunny afternoon. After my eyes got used to the darkness, as […]
