Traffic on expressways, trains on elevated corridors, metro viaducts passing between buildings and machines running at factory boundaries all push noise into offices, hospitals, schools and homes nearby. In growing Indian cities, many of these sources sit only a few metres from the people they affect. A solid wall can stop much of that noise,…
Noise costs businesses more than most owners realise. Staff lose focus in loud offices, hotel guests complain about lift and plant noise, and factories face notices when sound crosses the boundary. Good noise control solutions fix the problem at its source, along its path or at the room where people hear it. At Ecotone Acoustic…
Traffic on an elevated highway, trains on a metro viaduct and machines at a factory boundary all create noise that spreads far beyond the site. For the people in nearby offices, schools, hospitals and housing, that noise is a daily problem. A metallic noise barrier is one of the most common ways to control it…
A boardroom where every word can be heard in the next cabin. A hotel room that picks up the lift motor at night. A DG room that hums through the office above it. All of these are the same problem: sound is passing through a wall, floor or ceiling that is too light to stop…
When a fire alarm sounds inside a metro tunnel or an underground car park, the announcement that follows has one job: people must understand it the first time. In a long concrete tube full of fan noise and echo, that is harder than it sounds. This is exactly what SIT testing for tunnels checks. In…
Walk into a busy office, a new restaurant or a glass-walled conference room and you can usually hear the problem before you see it. Voices bounce off hard floors, glass and gypsum. People raise their voices to be heard, which makes the room louder still. Calls drop in quality, customers leave sooner and staff go…
Acoustical doors are the quickest way to fix the weakest link in a quiet workspace. Walk through any busy office and you will notice the same thing: the walls hold up fine, but the doors let everything through. Voices, phone calls, footsteps and machine hum slip right past them. If you are trying to figure…
Open floor plans look great on paper, but they often turn into echo chambers where phone calls, keyboard clatter, and footsteps blend into constant background noise. Perforated acoustic wall panels for offices solve this exact problem by combining a visually clean surface with functional sound absorption. If you have ever wondered why these panels are…
Noisy conference rooms, echoing auditoriums, and reverberating cinema halls affect comfort, communication, and productivity. If you are wondering how to install acoustic panels correctly in offices, hospitals, or large public venues, this guide walks you through the entire process, from planning to final mounting, with practical tips that any facility team can follow. Why Do…
Summary: NRC measures sound absorption inside a room on a 0 to 1.0 scale, while STC measures sound blocking between rooms, typically rated between 25 and 60 or higher. Use NRC-rated acoustic panels to control echo and improve speech clarity, and use STC-rated partitions, doors, and windows to stop noise from travelling between spaces. Most…
