Terry Montlick Laboratories LLC is a full-service acoustical engineering firm which designs and evaluates home theaters and critical listening rooms worldwide. Most of our services can be performed electronically, without the need for a site visit. We rely on photographs, dimensions, and other data you provide. The more complete this information is, the better we can design a theater that meets your specific sonic needs.

Our work is based strictly on scientific acoustical analysis, not guesswork or a hand clap. Every room we do is custom, yet we routinely work on theaters with budgets of under $10,000 and over $500,000.

Descriptions of specific services include only those items listed, and are limited to a single room. The scope of work on any project may be adjusted by the requirements of the job.

Our hourly consulting can be combined with any other services, or used as an option for small projects, with a one hour minimum.

$115.00/hr

No interior design is included or implied in any acoustical service.  Some designs are altered during the room design process by the interior designer, architect, builder, or home-owner.  Such changes will be charged extra at the Hourly Consulting rate. 

We evaluate a proposed   design. This includes up to 1 hour of correspondence (via telephone and/or email) to determine design information as accurately as possible, including room dimension, materials, furnishings, proposed speaker positions, etc.

Computer analysis is limited to reverberation times predicted from acoustical equations. report summarizes our analysis, and provides general recommendations.

$475.00

This evaluation is recommended for highest accuracy. We create a 3-D model of the proposed room from your measurements and drawings. We then run professional acoustical ray-tracing software^* which predicts standard acoustical quality metrics, including reverberation times (T30), clarity (C80), definition (D50), and front imaging accuracy. A detailed report summarizes our analysis, and includes  recommendations for acoustical treatment. Includes up to 2 hours of correspondence (via telephone and/or email).

* We use commercial quality ray-tracing software which has been optimized for small room acoustics. We do not use the consumer CARA software package (not a ray-tracer at all, but an image source modeler), which does not meet  professional acoustical simulation requirements for accuracy.

Premium Room Design

This service provides the same detailed level of acoustical analysis as our Premium Acoustical Evaluation, plus we design the room for you.

We  provide full B-sized schematics, including assembly drawings. These show all acoustical treatments necessary, and specific placement based on advanced ray-tracing simulation of your room. With our decades of experience in professional acoustics, we can provide a design that’s tailored to your needs. Design plans for all custom acoustical control devices are included.

All  Premium Room Design services include a reasonable and customary amount of email and telephone interaction with you, our client. Any work beyond this, such as requirement changes, will be billed at the Hourly Consulting rate.

Package D 

$1,495.00

Premium Room Design + Sound Isolation Design

This service adds sound isolation construction details to achieve a rating of NC-35 or better under typical external noise conditions.

Package DI 

+ $575 =

Premium Room Design + Sound Isolation Design + HVAC Specification

Adds specification of HVAC cooling requirements and duct work, based on room size and equipment.

Package DIH 

+ $345 = 
$2,415.00

+ $805 = 
$3,220.00

This is our pull-out-all-the-stops, top-of-the-line design service. Three on-site visits are typical. We work closely with your builder and architect to achieve fully integrated design aesthetics with ultimate acoustical performance.

Provided you fully and faithfully execute all of our design and subsequent acoustical adjustments, your room will achieve either Alpha Certification^®  or Alpha Multimedia  Certification.

Price is on a time and expenses basis. Hourly Consulting rate applies, plus ½ rate for travel time.

An estimate is provided after an initial evaluation. $1,200 deposit required.
