Acoustical Engineering Services

Studies, Reports, and Services

• Conduct studies in the fields of transportation noise (roadway traffic, aircraft and railroad), industrial noise control, ambient noise surveys, and architectural and building acoustics
• Conduct and prepare environmental impact reports (EIR's) and environmental impact studies (EIS's)
• Prepare and deliver expert legal testimony
• Develop and conduct specialized staff training
• Prepare general plan noise element and noise ordinance updates

Noise Monitoring and Software Use & Development

• Utilize sound level measurement and vibration measurement equipment which meet ANSI specifications for Type 1 sound level measurement equipment
• Conduct octave and narrow band frequency measurements and data analysis.
• Evaluate noise levels and associated impacts using computer models: Integrated Noise Model (INM - for developing aircraft noise contours for airports); Environmental Noise Model (ENM - for analysis and contour mapping for all environmental/industrial noise sources); Federal Highway Administration Traffic Noise Prediction Model, the Caltrans Sound 2000 Model traffic model and the recently developed Traffic Noise Model (TNM).
• Other custom software applications which have been developed in-house over the years are also used with regular frequency.
