Architectural Acoustics · Engineering · Manufacturing
Custom acoustic solutions for theatres, opera houses, stadiums, and entertainment centres worldwide — designed, manufactured and tuned by one engineering team.
Every family below ships from one plant under one QC regime — so a micro-perforated absorber and the plain lining beside it arrive sequence-matched, edge-banded and ready to read as a single wall. Published prices are indicative, FOB, and hold for sixty days.
Six system families, each drawn where it works in a hall. Hover a callout to read it — or open that family in the catalogue.
Hover a callout — the room explains itself.
Eight building types, eight distinct acoustic problems. The treatment follows the physics of the room — never the other way round.
Singers project unamplified over an orchestra; the room must carry 90 dB to the last balcony without blurring a syllable.
Spoken word dies above RT60 1.8 s. Stage towers swallow energy that auditoria need back.
Reverberance is the instrument — the job is diffusion and tunable absorption, never deadening.
Concrete bowls turn a crowd into 110 dB of standing echo; concourses need it stripped out.
A lecture hall is a speech machine: clarity at row 24 decides whether the back third learns.
One plenary, six configurations by Friday — isolation between them is the product.
NC-25 background and total bleed control, or the mix the studio approved never reaches the seat.
Multi-form rooms host a recital, a wedding and a congress in one week — acoustics must move with them.
A drama theatre mid-production, a shoebox concert hall, a divisible congress floor, a nine-screen cinema. Different programmes, one method: target, build, measure, adjust.
17,600 m² stage-tower and auditorium wall package: 12,500 micro-perforated Velo panels on stage-facing elevations, grain-matched Plano lining elsewhere, black Fibra wood wool through the fly tower.
Quanta diffusion arrays across rear and side walls with motorised Tessa banners, tuning the 1,400-seat shoebox between symphonic and amplified programmes.
Eleven Murus operable walls to 7.2 m subdividing the plenary into six halls, with Modulo perforated ceilings holding speech clarity in every configuration.
Nine premium screens lined floor-to-soffit in 50 mm Tessa absorbers over Tacet damped floors — background noise held at NC-25 with zero inter-auditorium bleed.
Six stages from first conversation to commissioned room. The model says what the room will do before a single panel is drilled — and the final measurement has to agree with it.
We start with the programme, not the panel: what the room is for, who performs, who listens.
Impulse responses on retrofits, ray-trace and FEM models on new builds. Targets in numbers, not adjectives.
Perforation, cavity and layout engineered to the model — then drawn to the millimetre for fabrication.
CNC perforation, veneer sequencing and finishing in one 30,000 m² plant under ISO 9001.
Our crews or your contractor under our supervision — setting-out files, jigs and torque specs included.
Commissioning measurements against the model. We adjust until RT60 lands inside ±0.1 s of target.
Measured absorption · EN ISO 354
The fraction of sound energy a surface removes at a given frequency, measured per octave band from 125 Hz to 4 kHz in our EN ISO 354 reverberation room. α 0.90 means 90% absorbed; the curve matters more than any single point.
Noise Reduction Coefficient — the average of α at 250, 500, 1000 and 2000 Hz, rounded to 0.05. One honest number for comparing systems, blind to the bass behaviour a hall lives or dies by. We publish both.
The time sound takes to decay by 60 dB. Opera wants 1.6–1.9 s; spoken drama under 1.1 s; a cinema near 0.4 s. We tune to the programme — and commission to ±0.1 s of target.
“A room is an instrument. We build the parts you don't see and tune the part you can't — the air.”
AKOVRA began in 2009 as a single CNC perforation line in Guangzhou, taking on the drilling patterns other workshops refused — half-millimetre apertures, six-figure hole counts, veneer that had to survive both. The acoustics came with the territory: clients kept asking not just for the panel, but for the number the panel had to deliver.
Seventeen years later that question is the whole company. An in-house reverberation room and impedance tube mean every published coefficient is ours, measured, not borrowed from a lookalike datasheet. A 30,000 m² plant puts perforation, veneer sequencing, upholstery and finishing under one roof. And a turnkey division carries the responsibility from simulation through commissioning, so when the brief says RT60 1.7 seconds, one party is answerable for it.
Akovra is a made word. We took akouein — the Greek “to hear”, the verb under every “acoustic” — and bent it until it belonged to no dictionary and to us. The oldest verb in our trade, finally proprietary.
Founded in Guangzhou on a single CNC perforation line, quoting the patterns nobody else would.
First export package — a Gulf conference centre — establishes the FOB delivery model.
In-house acoustic laboratory commissioned: reverberation room and impedance tube to EN ISO 354.
Turnkey division formed — simulation, manufacture, installation and commissioning under one contract.
FSC® chain-of-custody certified; plant expanded to 30,000 m².
Central Asia programme opens — a flagship drama-theatre stage rebuild enters production in Ashgabat.
