Reverberation and speech intelligibility calculated room by room, with the exact area and class of acoustic treatment needed — and what it will cost.
A design-stage report, calculated from your room dimensions and surface finishes.
No site visit needed. Room acoustics is calculated, not measured. Send drawings or measured dimensions plus photographs of each room and we have everything the calculation requires.
Who this report is for
- Restaurants and bars that are too loud for conversation
- Open-plan offices with speech-privacy and distraction problems
- Schools needing acoustic compliance for building control or a funding condition
- Healthcare projects with reverberation criteria
- Places of worship, community halls, studios, gyms and podcast rooms
- Projects targeting acoustic credits in a sustainability rating
What the report contains
- Summary and a prioritised recommendation list
- Room-by-room schedule with volume, surface areas and existing finishes
- Existing reverberation time calculated per octave band (Sabine and Eyring)
- Target reverberation time and the applicable criterion
- Absorption schedule — the required square metres per room, the absorption coefficient each product must meet, and where to place it: ceiling, upper walls, baffles or rafts
- Product-agnostic specification with named example products across price points
- Speech intelligibility commentary where relevant
- Building services noise assessed against NR or NC design criteria
- Open-plan speech-privacy strategy including distraction distance, where relevant
- Indicative budget range for the treatment
- Appendices with the calculations for every room
Standards we write to
Tell us which country the project is in and which authority the report must satisfy, and we assess against the right framework.
| Region | Assessed against |
|---|---|
| United Kingdom | BB93 for schools, HTM 08-01 for healthcare, BREEAM Hea 05 |
| EU / international | ISO 3382-2, EN 12354-6 |
| United States & Canada | ANSI/ASA S12.60, ASHRAE NC/RC criteria, LEED and WELL acoustic credits |
| Australia & New Zealand | AS/NZS 2107 |
What we need from you
- Floor plans with room dimensions, or measured dimensions per room
- Ceiling heights and existing surface finishes for floor, walls and ceiling
- Photographs of each room
- Room use and how many people occupy each
- Any criterion you must meet
Your turnaround starts when we have all of this — not when you pay.
What this report is not
- Not supply or installation of acoustic treatment. We specify it, you buy and install it. We take no supplier commission
- Not a sound insulation assessment between rooms — that is the Sound Insulation Design Report
- Not a noise-at-work assessment
- Not a measured reverberation test on site
Price and turnaround
| Tier | Turnaround | Price |
|---|---|---|
| 1–3 rooms | 5 working days | $545 |
| 4–10 rooms | 6 working days | $1,145 |
| 11+ rooms or a whole building | 8 working days | $2,095 |
Prices in US dollars, shown in full — that is the total you pay. Two rounds of revisions included within 30 days.
How it works
- Choose your report. The price you see is the price you pay.
- Tell us about the project. A short brief here, a fuller intake after checkout.
- We do the work. Modelling, calculation and drafting, accelerated by our own tooling.
- An acoustician reviews and signs it. Every report is manually reviewed and signed by a professional acoustician before it reaches you.
Questions
My restaurant is just too loud. Is this the right report?
Yes. Excessive loudness in a restaurant is almost always reverberation, not the sound system. We calculate how much absorption the room needs and where to put it.
Can you work from photos and dimensions?
Yes — that is exactly what this report is designed around. Room dimensions, surface finishes and photographs are enough for a reliable calculation.
Will you tell me what it will cost to fix?
We give an indicative budget range based on the specified absorption area and typical product pricing. Actual cost depends on your installer and product choice.
Do you cover building services noise?
Yes, against NR or NC criteria, where you supply the ventilation and mechanical data.
