Acoustic Treatment for Hospitals: What the Specification Needs to Cover

unidus June 16, 2026

Acoustic treatment for hospitals is consistently under-specified. WHO guidelines set a ceiling of 35 dBA for patient-occupied areas during the day, 30 dBA at night. Most hospital wards run at 50–60 dBA under normal operation, with ICUs running higher still, because equipment noise alone pushes well past the threshold before any human activity is added. For patients with limited physiological reserves, that gap shows up as disrupted sleep and slower recovery. For the architect on

6 Partition Wall Sound Insulation Methods That Work in Office Fit-Outs

unidus June 12, 2026

Partition wall sound insulation is the application of materials and construction methods to reduce airborne sound transmission between adjacent spaces, measured by Sound Transmission Class (STC), where a higher number indicates better acoustic isolation. In practical terms, partition wall sound insulation covers every design and material decision that affects how much sound passes through an interior dividing wall, whether that wall is gypsum board on studs, a glass partition system, or a modular demountable product.

A Guide to Mineral Fibre Acoustic Ceiling Tiles

unidus June 8, 2026

Mineral fibre acoustic ceiling tiles are suspended ceiling panels made from natural and recycled mineral materials, designed to absorb airborne sound within a space and, in higher-performance products, to reduce sound transmission through the ceiling plane into adjacent rooms. But not all mineral fibre tiles perform the same way. NRC, CAC, fire rating, humidity resistance, edge profile, and surface texture choices all affect which product is right for which space. Specifying without understanding those differences

Why Metal Ceiling Panels Are Gaining Ground in Commercial Acoustic Design

unidus June 4, 2026

Commercial interiors have always had a complicated relationship with metal ceilings. For much of the last century, metal overhead read as industrial. Think warehouse roofing, factory sheds, the underside of a railway platform. The assumption followed naturally: hard materials make poor acoustic choices. For unperforated metal over hard floors and bare walls, that assumption holds. But perforated metal ceiling panels, backed and installed correctly, are a different product in a different performance category. Key Takeaways

Acoustic Consultant in Bangalore: The IT Park Standard

unidus May 29, 2026

Bangalore’s IT corridors have quietly set a benchmark for commercial acoustic design in India. Step into a well-spec’d office at Embassy Tech Village, Manyata Tech Park, or the Whitefield clusters and you’ll notice it – or rather, you won’t notice it. Conversations don’t bleed between floors. Conference rooms don’t echo. The noise floor sits at a level where people can actually think. The architects and project management consultants behind those projects didn’t get there by

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
