Acoustic Insights & Advice

Flutter echo is a fast buzzing repeat between parallel hard walls. See why RT60 can miss it and how to break the reflection path.

WELL v2 has a dedicated Sound concept, and every project starts with a sound map. See what it requires and how it pairs with BS ISO 22955.

Conservation officers approve reversible acoustic treatment. See what Historic England allows and why secondary glazing suits listed windows.

Untreated corridors send noise into the rooms either side. See impact-resistant treatment that fits tight ceiling voids.

Soundproofing stops sound moving between rooms. Acoustic treatment tames echo inside one. Learn which your problem needs before you spend.

Ceiling height, services and exposed soffits decide whether you need tiles, baffles or rafts. Here's how to choose the right acoustic ceiling for your room.

One page, nine UK acoustic standards. Find which figure applies to your building, from BB93 and HTM 08-01 to Approved Document E.

Treating classrooms alone leaves halls and corridors echoing. See BB93 across a whole school and how to phase the work.

Untreated classrooms blur speech for the pupils who need it most. See the BB93 limit of 0.6 to 0.8 seconds and how treatment meets it.

Airborne and impact noise are rated and fixed differently. See the Part E figures and why one fix rarely solves both problems.

Glass meeting rooms echo inside and leak sound outside. Echo control and speech privacy are different problems with different fixes.

HTM 08-01 sets Noise Rating limits for wards, theatres and clinics. Learn the NR values and why infection control decides every material.

Class 0 alone no longer satisfies UK building control. See what Euroclass B-s1,d0 and C-s3,d2 mean and which your panels need.

Echoey video calls come from the room, not the software. Learn where to place absorption around the microphone and camera.

Ceiling rafts float below the deck, and the air gap boosts low-frequency absorption. See where they beat flush tiles and baffles, and what to check first.

Libraries carry sound across open floors and shelving. See how ceiling absorption and screens separate silent study from group work.

The Noise at Work Regulations set three legal dB(A) thresholds. See what each triggers and why engineering controls come before ear defenders.

Acoustic pods add sound-isolated rooms to an open-plan office without building work. Learn what they block, what to check on ventilation and fire, and sizes.

Stretched fabric systems give large walls a seamless, joint-free finish over a real absorber. Here's when they justify the cost over standard acoustic panels.

Hospitals need hard, wipeable surfaces that echo. See how HTM 08-01 NR targets and infection control are met together.

BS ISO 22955:2021 sets different acoustic targets by activity, not one for the whole office. See what it asks for and where fit-outs fall short.

Standard interior panels fail fast on production floors. See what makes industrial acoustic panels different, what they can't do, and how to specify them.

Sports halls get their own BB93 targets. See why ceiling baffles are the efficient fix and how to keep whistles and PA announcements clear.

Guests notice every door slam and TV through the wall. See how Approved Document E and lobby treatment are solved as one project.

Loft conversions and extensions often trigger Approved Document E. See the 45 dB and 43 dB figures and when a room only needs treatment.

PET felt panels are made from recycled bottles and take colour and shape well. See where they match mineral wool and where they fall short.

Absorption removes sound energy, diffusion scatters it. Learn which one your room needs, and why using only absorbers can sound dead.

Showrooms are loud because they look open. Bring reverberation down with ceiling and upper-wall absorption without cluttering the floor.

Some UK projects legally need UKAS-accredited sound testing. Learn when Part E testing applies and how Robust Details can exempt you.

Microperforated panels absorb sound through thousands of tiny holes in a face that reads as solid. See how they're tuned, where they fit, and what to avoid.

Timber slat acoustic panels put real wood on the wall over a felt absorber. See how slat spacing sets performance and when they suit better than fabric.

Restaurants get loud at peak service, not at the empty-room measurement. Treat for full capacity with easy-clean, design-led finishes.

10dB sounds twice as loud but is ten times the energy. See the 3dB and 10dB rules, dB(A) weighting and why they shape treatment choices.

Custom acoustic features suit odd geometry, lit ceilings and signature walls. See what bespoke involves, its cost in time, and how to brief it.

A studio has to keep noise out and control the sound inside. Learn why isolation and treatment must be designed as one system.

BB93 sets reverberation and background noise limits by room type in UK schools. See the figures, the SEN targets and how compliance is tested.

RT60 is the time sound takes to fade by 60 dB. See the Sabine equation, good targets by room type and why treatment plans differ room to room.

Acoustic lighting combines a light fitting with a sound absorber. See where it works, why it can't replace panels, and what to check on wiring and heat.

Acoustic furniture puts absorption into seating and partitions a room needs anyway. See where it helps, what it can't replace, and what to check on fire safety.

Acoustic ceiling tiles drop into a standard grid and turn the whole ceiling into an absorber. See when they beat baffles and what the void above changes.

Noise at work rules start at 80 dB(A) and end at 87 dB(A). See what employers must do at each level and how absorption helps.

Approved Document E sets exact dB figures for new builds and conversions. See the thresholds, the testing rules and where projects get caught out.

3D acoustic panels use folds, waves and facets to scatter and absorb sound while giving a wall real depth. Learn when they beat flat panels and what to check.

Acoustic wall panels cut echo inside a room, they don't block sound between rooms. Here's how to choose thickness, core, finish and fixing without overpaying.

Speech and music need opposite reverberation times. See why one auditorium rarely does both well and how to design for actual use.

Open-plan offices get loud by mid-afternoon. See how BS ISO 22955:2021 sets targets by activity and how to fix the floor.

Fibreglass, mineral wool, PET felt and foam all absorb sound differently. See real NRC ranges, fire and handling trade-offs for each.

Acoustic screens add speech privacy between desks without building walls. Learn how height and sightline decide performance, and which type suits your office.

Sound masking adds a calibrated background hum that makes speech harder to follow. See where it works, and why it needs panels too.

Listed galleries echo, and most fixes are off limits. See reversible options, sculptural panels and how to protect audio exhibits.

Perforated and grooved acoustic wood panels look like continuous timber but let sound through to an absorber. Learn how the pattern sets performance.

NRC averages absorption at four frequencies and hides bass performance. Learn to read ratings, Class A to E, and real material ranges.

Ceiling baffles treat the surface most rooms leave bare. Learn how they work, where they beat wall panels, and what to check on spacing, void and fire class.

BB93 sets a 0.4 second reverberation limit for SEN and hearing-impaired rooms, tighter than any mainstream classroom. Here is what it demands.

A village hall must suit toddlers, meetings and weddings. See a budget-conscious, durable treatment plan that works for every use.
