Testing and Measurements service description

We Offer a wide variety of on-site acoustic testing such as:

  • Noise measurements in standard decibel ratings (dB-A weighted) – Used for compliance with local, state, and/or federal requirements of noise level
  • FIIC/AIIC – Field/Apparent Impact Insulation Class – Used for measuring the sound transmission of a ceiling/floor structure in commercial spaces, houses, and apartments
  • FSTC/ASTC – Field/Apparent Sound Transmission Class – Used for measuring the sound transmission of a wall structure in apartments, houses, commercial spaces and condominiums
  • Noise Dosimeter Testing – A simplified sound level meter is attached to an individual in order to assess their noise exposure during a predefined period
  • Noise Surveys – OSHA compliance and other Federal agencies when properties such as houses, apartments and condominiums are located near noise sources like Airports, Train Tracks, Highways and Freeways, Manufacturing Plants, Sewage Treatments Plants, and Power Stations noise surveys are timed studies detailing the noise levels for a specific time period
  • Noise Spectrum Analysis — Used for determining what frequencies in the audio band a particular noise is coming from when measured from an adjacent house, apartment, condominium or commercial space
  • Vibration Analysis – Used for tracking down vibration coming from machinery, and sometimes to determine whether a machine assembly is in balance. We can provide both real-time and long term logging of vibrating structures.
  • Acoustic Facts for Manufacturers – Acoustic facts is a world leading expert in interior acoustics. Acoustic data that has been certified, evaluated and broadcasted by Acoustic Facts gives credibility for the use of the product throughout the design process. Performing calculations with evaluated products imply safe design of any room and satisfied end users.

We are able to offer most ASTM, MSHA. and ISO tests in the acoustic area.
