From our geographically central location, Soundscape Engineering LLC's acoustical consultants and noise and vibration control engineers serve clients located throughout North America - in Chicago, Illinois; Detroit, Grand Rapids, Lansing, Ann Arbor, and Petoskey, Michigan; Milwaukee and Madison Wisconsin; Indianapolis, Fort Wayne, South Bend, and Northwest Indiana; Los Angeles, California; Vancouver, British Columbia; Dayton and Cincinnati Ohio, Winnipeg Manitoba; Saskatoon and Regina Saskatchewan; and elsewhere. Our engineers consult on issues of room acoustics, sound isolation, speech privacy, HVAC noise control, building vibration, and exterior noise impact. They also provide acoustic and vibration measurement services.


Soundscape Engineering provides noise level measurement services to assess noise in communities and in buildings. We measure noise generated by machinery, people, and myriad other sources.

We measure room acoustical characteristics and the sound isolating performance of building elements, such as the Sound Transmission Class (STC) of walls, doors, windows, and floors.

Measurements are performed in accordance with local noise ordinances and ANSI, ASTM, and other national standards. These standards include the following:



  • Speech Intelligibility testing per NFPA 72
  • ASTM E966 Standard Guide for Field Measurements of Airborne Sound Attenuation of Building Facades and Facade Elements
  • ASTM E336 Standard Test Method for Measurement of Airborne Sound Attenuation between Rooms in Buildings
  • ASTM E1007 Standard Test Method for Field Measurement of Tapping Machine Impact Sound Transmission Through Floor-Ceiling Assemblies and Associated Support Structures
  • ASTM E413 Classification for Rating Sound Insulation
  • ASTM E1332 Standard Classification for Rating Outdoor-Indoor Sound Attenuation
  • ASTM E1573 Standard Test Method for Evaluating Masking Sound in Open Offices Using A-Weighted and One-Third Octave Band Sound Pressure Levels
  • ASTM E1130 Standard Test Method for Objective Measurement of Speech Privacy in Open Plan Spaces Using Articulation Index
  • ASTM E2638 Standard Test Method for Objective Measurement of the Speech Privacy Provided by a Closed Room
  • ASTM E1110 Standard Classification for Determination of Articulation Class
  • ANSI/AHRI Standard 260 Sound Rating of Ducted Air Moving and Conditioning Equipment
  • AHRI Standard 370 Sound Performance Rating of Large Air-cooled Outdoor Refrigerating and Air-Conditioning Equipment
  • ANSI/ARHI Standard 575 Method of Measuring Machinery Sound Within an Equipment Space
  • ANSI/ASA S12.54 / ISO 3744 Acoustics - Determination of sound power levels and sound energy levels of noise sources using sound pressure - Engineering methods for an essentially free field over a reflecting plane
  • ANSI/ASA S12.57 / ISO 3747 Acoustics - Determination of sound power levels and sound energy levels of noise sources using sound pressure - Engineering/survey methods for use in situ in a reverberant environment
