How to Specify Acoustic Ceiling Panels for Large-Volume Open Spaces

unidus May 25, 2026

Large-volume commercial spaces have a fundamentally different acoustic problem from small meeting rooms. Sound travels farther, reflects off more surfaces, and takes longer to decay. A 3,000 sq ft open-plan floor is a different design challenge from a 25-person conference room, and specifying acoustic ceiling panels for it requires more than selecting a tile with a high NRC rating. This guide covers coverage calculations, panel types, performance targets, and the specification variables that matter most

6 Things to Check When Specifying Acoustic Felt Panels for High-Traffic Spaces

unidus May 21, 2026

Acoustic felt panels have become a standard specification in commercial interiors. They absorb sound well across the mid-frequency range, come in an extensive colour palette, and carry a credible sustainability story given that most are made from recycled PET fibre. High-traffic spaces impose conditions that low-use environments never will. Panels near entrances face cleaning chemicals. Those in corridors get knocked by trolleys, and panels in canteen areas contend with intermittent moisture and food service activity.

How Perforated Metal Ceiling Systems Handle Noise in Large Commercial Buildings

unidus May 16, 2026

Noise management in large commercial spaces is rarely simple, and that’s why the ceiling is often the first surface a specifier looks to. Perforated metal ceiling systems have become one of the most commonly specified acoustic solutions in large-volume commercial buildings. But how they work acoustically, and when they’re genuinely the right choice, is worth understanding before committing to a specification. Key Takeaways What Makes Large Commercial Buildings Acoustically Difficult Large commercial spaces face three

How Soundproof Fabric Is Used in Commercial Installations

unidus May 12, 2026

Soundproof fabric doesn’t get much attention in specification documents. It usually shows up as a colour selection, and then the conversation moves on to NRC ratings and mounting heights. But the fabric in a fabric-wrapped acoustic panel, or in a fabric-faced ceiling system, is doing something specific, and getting it wrong leads to systems that underperform against their specified ratings. At Unidus Acoustics, this is one of the more common specification gaps we encounter on

Do Noise Cancelling Wall Panels Actually Work?

unidus May 8, 2026

‘Noise cancelling wall panels’ is a widely used but imprecise term. These panels do not cancel noise the way headphones do. They absorb sound within a space to reduce echo and reverberation, which is a different problem from blocking sound between rooms. This article explains the distinction, what NRC ratings mean for commercial specifications, and where panels actually make a measurable difference. Key Takeaways What Does ‘Noise Cancelling’ Mean for Wall Panels? In consumer electronics,

How White Acoustic Panels Perform in Minimalist Commercial Interiors

unidus May 4, 2026

White acoustic panels perform identically to any other colour of the same product. Acoustic absorption happens inside the panel, through the core material, not at the surface. What determines performance is the finish type; a white acoustic fabric or perforated surface is acoustically transparent, while a painted or coated hard surface is not. Colour is not the variable that matters. This article explains how different types of white acoustic panels behave in commercial interiors, where

How to Choose the Right Fabric Panels for High-Use Environments

unidus April 30, 2026

Fabric panels are one of the most frequently specified acoustic solutions in commercial interiors. They absorb sound across a broad frequency range, take customised colours and finishes without much fuss, and work across a wide range of project types. But in high-use environments, the specification requirements go well beyond what a standard product datasheet addresses. A panel that performs on day one but degrades after eighteen months of cleaning cycles and daily contact is a

Acoustic Treatment for Multipurpose Halls: One Room, Multiple Demands

unidus April 25, 2026

Most institutional buildings have at least one of these spaces: the seminar hall, the multipurpose auditorium, the event space, or the town hall room. The idea is the same: a single room that needs to work for a board presentation on Tuesday, a cultural performance on Friday, a graduation ceremony the week after, and something completely different the month after that. The acoustic challenge this creates is more difficult than it first appears. Speech and

7 Questions to Ask Before Selecting an Acoustic Consultant in Noida

unidus April 21, 2026

Noida’s commercial pipeline has changed considerably. New office developments along the Noida-Greater Noida Expressway, in Sectors 62, 132, and 140A, and across the emerging institutional corridor have brought in tech firms, global capability centres, and institutional tenants whose fitout briefs routinely carry acoustic performance targets. GCC leasing in Noida grew significantly through 2024, and Grade A office absorption in the region continues to rise. For architects and interior designers handling these projects, selecting the right

Soundproofing vs Acoustic Treatment: What You Actually Need

unidus April 17, 2026

There’s a conversation that happens on almost every commercial fit-out: a client walks into the finished space, frowns at the ceiling, and says, “It’s too loud. Can you soundproof it?” Nine times out of ten, soundproofing isn’t what they need. They need acoustic treatment. And the confusion is understandable. Both disciplines deal with sound. Both involve adding materials to a space. But they solve fundamentally different problems, and specifying one when you need the other

What NRC Testing Results Actually Tell You About Acoustic Panel Performance

unidus April 13, 2026

A product datasheet says NRC 0.95. Another says NRC 1.05. You’re specifying acoustic panels for a 3,000 sq ft open office, and you need to make a decision. Which panel performs better? The answer isn’t as obvious as the numbers suggest. NRC testing is one of the most useful tools in acoustic specification. It’s also one of the most frequently misunderstood, partly because of how manufacturers present results and partly because a single number can’t

Office Acoustics: How to Reduce Echo and Improve Speech Privacy in Open-Plan Spaces

unidus April 8, 2026

The open-plan office was supposed to solve something. Collaboration, the energy of a shared workspace, and visibility across teams. In many ways, it delivered. But the acoustic side of things? That’s where the problems started piling up. If you’ve ever handed over an open-plan office and had the client call back a few weeks later about the noise, you know what a gap in office acoustics planning looks like. The noise isn’t just irritating. It

What Makes an Acoustic Panel Genuinely Eco-Friendly (And What’s Marketing)

unidus April 4, 2026

The word “eco-friendly” has been doing a lot of heavy lifting in building product marketing for years. Acoustic products are no exception. Manufacturers routinely describe their acoustic panels as green, sustainable, or environmentally responsible, and the evidence behind these claims varies enormously. For architects and interior designers specifying materials for commercial projects, this matters more than it might seem. When something ends up on a specification sheet, you’re implicitly vouching for it. Knowing what to

Acoustic Consultant in Gurgaon: What Corporate and Institutional Projects Demand

unidus March 31, 2026

Gurgaon’s project pipeline has shifted considerably. Commercial towers, institutional campuses, and co-working developments now carry acoustic requirements that appear in briefs far more regularly than they did a decade ago. Clients are more aware of the problem, and occupants are quicker to raise complaints once a space is occupied. With building typologies ranging from glass-heavy corporate headquarters to multi-use auditoriums, the acoustic demands vary sharply from one project to the next. For architects and designers

Best Acoustic Consultant in Delhi: What to Look for Before You Shortlist

unidus March 27, 2026

Finding an acoustic consultant in Delhi is not particularly difficult. Finding one who delivers on what they promise during the pitch is a different matter altogether. Most vendors in this space can walk you through a catalogue, quote NRC ratings, and assure you that everything will be fully custom-made. Some actually mean it. Others are working with a very loose definition of “custom.” And by the time you find out which category you’re in, the

Phone Booths vs. Meeting Pods: Which One Does Your Office Need?

unidus March 23, 2026

Open-plan offices promised collaboration. What they often delivered was noise, distraction, and a constant scramble for private space. Now, two products keep coming up in commercial project briefs: phone booths and meeting pods. They look similar from across a floor plate, but they solve different problems, and specifying the wrong one tends to surface fast in post-occupancy feedback. This piece breaks down the distinction, outlines where each solution performs best, and covers what to verify
