How much does a design cost (some typical fees)?

Remote Room Testing begins at $500 and a multi-room commercial facility design will have services beginning at the $10,000 range. A single room audiophile or control room design would typically be in the $4,000 range. Important to understand is that EVERY job has its own factors and its own properly defined scope of work. Design and Consulting costs are quoted per job.

The resulting design must support not only the scope of work but the people executing it. From a napkin sketch to a 30-page document set, the design intents and specifics have to be clearly communicated. HdAcoustics follows standard architect protocol: program development, concept creation, design development, documentation, bid review, construction support and final verification.

How can remote acoustical design possibly work?

Remote Design Works because today’s technology allows detailed and timely communications, because advances in acoustical modeling processes/software, and because the remote design process HdAcoustics utilizes has been perfected over the past twenty years.

Client preparation and role through the process?

Inspiration is a big part of the design process and what inspires our client’s always drives the design, very much becoming part of the final space. Please feel free to share what inspires you be that a musician, another room of your type, an architectural space that has nothing to do with your project, etc…


Timely communications- Accurate Communications-Clarity in Needs/Goals are a big part of the client’s role in every project.

Client’s are needed to stay engaged and are encouraged to ask all questions (big and small). It’s much better to over-communicate than slide through areas that should be developed or closely reviewed.

Client’s are required to share accurate information of the site and it’s existing factors. A ground up situation and a rennovation have different. It is also common to bring in local professionals (builders/architects/etc) to review the site conditions.

What is a small room acoustics specialist?

Acoustically, a small room is ~10,000 cubic feet or smaller. A specialist in small room acoustics understands the unique functions and needs of purpose designed studios, great HiFi room and reference level home cinema. There is a DIRECT correlation between the structure and the low frequency response. Additionally, the speaker location(s) and the listner location(s) are hugely important in optimizing the final response. HdAcoustics has specialized in small room acoustics since it’s opening.

How long does a design take?

A design might take as little as two weeks (on a small project) and we have projects that are still making progress years after the initial communications. There is a natural ebb and flow of communication and workflow that factors the project and people’s needs. A fully designed HiFi room may take up to a month for an initial concept and an equal amount of time for the document set. A multi-room commercial studio might take multiple months to complete the design and document set. In jobs requiring permit review/approval, the design timelines are established as the team is fully assembled and the local requirements are understood per each project.

What about permits?

The documentation needed to be granted a building permit from your local building and safety department is entirely defined by your local codes. HdAcoustics is neither a licensed architect nor a structural engineering firm. Depending on your cities’ classification of your space and their ordinances, HdAcoustics will work with your architect or builder on the document set for review and permit. We will bring in our partners (builders, architects, or structural engineers) to a clients team where appropriate. There are situations where our drawings have been able to be submitted and the permit is issued to the licensed general contractor.

What is acoustical modeling?

The simulation of how sound reacts within the targeted space is acoustical modeling. The term “acoustically significant” is important and that is where 15+ years of professional room modeling experience comes into play. We strive to use and command the best tools, but acoustical modeling falls under the slang term “GIGO” (garbage in=garbage out). The surfaces have to be assigned their proper values, but not every item within a room is acoustically significant. The speaker locations and qualities are crucial to apply properly and with purpose to have correlation to real life.

What is low frequency spatial mapping?

We can measure (and/or model) the frequency of a sound, we can measure (and/or model) the amplitude of sound and we can model (and/or physically) measure distance. If you grid the frequency and amplitude of sound energy in the horizontal plane of a room, it can be very revealing and helpful in determining the proper low frequency control systems (er, bass trapping) in a given room. This process is also able to pre-qualify the location of a subwoofer or multiple subwoofers.

What is Remote Room Testing (RRT)?

RRT is a service developed to take the burden from our client’s to learn how to operate and analyze the great room test apps like REW, ARTA and HolmImpulse. It is also a way to gain extremely valuable project information without the additional costs of travel. HdAcoustics has spent years perfecting a method to remotely capture acoustical data that can be processed in many meaningful ways. We understand that the information in a graph has to connect to the experiences people hear in a given room. There is no end to this passion and curiosity to gain more data points- different rooms, different speakers, and different human preferences.

Sound Isolation Consulting?

Determining how much sound level will transmit (and the frequency content of that sound energy) from one location to another is the essence of sound isolation consulting. Impact noise is another important part of Sound Isolation Consulting.

In real-life, the sound transmission issue could be the family above you intruding on your ATMOS compliant cinema experience. This could be drums bleeding into an isolation booth making tracking difficult. It could even be a train in the distance covering of the low level details of your otherwise amazing stereo listening experience. We utilize and properly apply the very best noise and vibration simulation tools.

Will you build or buy acoustical materials?

The best rooms are purposed dimensions, purposed construction, and full surface site-built acoustical systems. That said, HdAcoustics offers options using materials that are modular from commercial vendors or designed to be built by clients.
