Rail, Highway & Air

Acentech has the experience, tools, and technical staff available for large and small transportation projects. Several staff are Board Certified by the Institute of Noise Control Engineering. Several hold PhDs. Others are Professional Engineers.

We have 60 years of direct experience in:

• Development of criteria for design and planning of transit systems
• Prediction and control of noise and vibration propagation into the surrounding communities from transit facilities
• Measurement and analysis of noise and vibration from transit systems, railroads, and industrial facilities
• Mitigation design such as sound walls, ballast mats, and building sound insulation treatments
• Noise and vibration impact studies and compliance with local, state, FHWA, FTA, FRA, and NEPA/CEQA requirements.
• Agency and community interaction
• Transit station acoustics and sound system design

We maintain and use a full inventory of noise and vibration instruments which are laboratory calibrated and traceable to the National Institute of Standards and Technology (NIST).
