Erich Thalheimer is an acoustical engineer with more than 25 years of experience in professional practice and
education, and has earned a national reputation in the area of construction noise control. His broad range of
experience includes noise assessment and mitigation for transportation (highway, airport, and railroad)
projects; construction noise and vibration projects; stationary source and operational noise projects; interior
acoustics projects; applied noise and vibration research; and product noise and vibration testing. He has
provided expert witness testimony to clients in the area of noise analysis and mitigation, and has presented
numerous seminars to the engineering community on noise measurement, analysis and control. Erich is an
expert in area of noise and vibration measurement and analysis.

Erich’s accumulation of knowledge and successful leadership on the Central Artery/Tunnel (The Big Dig)
Project’s noise control program (,%20NCEJ,%2048(5),%20Sep-Oct%202000.pdf) earned him
the status as Board Certified by the Institute of Noise Control Engineering in 2001. For his work, Erich was
honored by the American Road & Transportation Builders Association with an ARTBA Globe Award in 2003,
and received the Artery Business Committee’s ABC Excellence in Building Award in 2001. He has also
appeared in several TV documentaries, newscasts, and newspaper articles regarding construction noise
control. Erich has shared these experiences with the engineering community through more than a dozen
published technical papers. Erich recently concluded his work with FHWA and the Volpe Center to establish a
new national policy and assessment procedure for construction noise, entitled Roadway Construction Noise
Model (RCNM), which was officially released by FHWA in February 2006 and is available for downloading at More recently he completed work with the New York City DEP to
update and improve the NY City Noise Regulations which take effect in July 2007 and can be seen at For this effort, Mr. Thalheimer received a 2009 ACEC Silver Award
from the American Council of Engineering Companies as well as the 2010 NHCA Safe-In-Sound Award from
the National Hearing Conservation Association.

Erich has also been a contributing member of several technical standards committees including ANSI S12 for
community noise, ISO 2631/5349 for human vibration, and IES S10 for roadway lighting.
