Acoustic Analysis and Treatment Planning

Poor acoustics are not just an annoyance — they are a productivity and safety issue in offices, and a barrier to participation in worship and event spaces. If your team is raising voices to be heard across an open-plan floor, or if worshippers in the rear pews are missing half of what is said from the front, the problem is measurable and treatable.

We work with office managers, facilities directors, church leaders, and event venue operators across Calgary. Heritage buildings, modern open-plan offices, large event halls, and intimate meeting rooms each present different acoustic challenges, and each deserves analysis based on actual measurement rather than assumption.

Our on-site measurement day captures three key indicators: reverberation time, which describes how long sound lingers in the room; speech transmission index (STI), a standardized score from zero to one that predicts how clearly spoken words will be understood; and background noise levels, which set the floor against which all speech must compete. Together these three numbers give a complete picture of how the room behaves.

A STI score above 0.60 is generally considered good for offices and worship spaces. We measure your current score and model how proposed treatments will move it. Reverberation time targets vary by room type and use, and we apply the appropriate standard for your specific situation rather than a one-size-fits-all benchmark.

After measurement, we identify the primary reflection paths and flutter-echo sources that are driving the problems. The treatment plan specifies the type of acoustic material needed, where it should be placed, and the approximate quantity required. We do not recommend a single brand or product; we describe the performance characteristics, so your contractor can source materials that meet the specification.

The plan includes coordination notes written for architects and contractors, so the people doing the work understand the intent behind each element. A before-and-after prediction report shows the expected improvement in measurable terms, giving everyone involved a clear target to build toward.

Calgary has no shortage of buildings where the interior itself is part of the experience — churches with ornate woodwork, event halls with period detailing, offices in converted heritage structures. Acoustic treatment in these spaces requires care, because the wrong approach can damage the character that makes the building worth preserving.

We routinely work in architecturally sensitive spaces. Treatment options such as upholstered pew cushions, fabric banners, and concealed ceiling baffles can significantly improve acoustics with minimal visual impact. Every recommendation in a heritage context is chosen with the appearance of the space in mind, and we note any trade-offs between acoustic performance and visual preservation clearly in the plan.

Pastor Chairs Consulting is an independent consulting firm, not a contractor or supplier. We specify what is needed and then work alongside your chosen contractor to ensure the plan is understood and executed correctly. Because we have no financial interest in which products are purchased or which contractor is hired, our advice remains independent and unbiased throughout.

A post-installation measurement visit is included in every engagement. We return after the treatment is in place, take the same measurements we took at the start, and confirm whether the targets have been met. If something has not landed as predicted, we identify why and advise on next steps — giving you a factual record of the outcome rather than a subjective impression.

Every building has its own acoustic fingerprint, shaped by its dimensions, materials, and the way people use it. Generic advice rarely fits. Pastor Chairs Consulting's local roots mean we have worked in the kinds of spaces Calgary is built from — the community halls, the downtown office floors, the sanctuaries — and we bring that accumulated understanding to every new engagement.

We know the contractors and architects who work in this city, and we write our coordination notes with that audience in mind. The result is a treatment plan that does not gather dust on a shelf but moves smoothly into the hands of the people who will bring it to life in your space.
