Principal Acoustic EngineerOmny Acoustics 2019 - PresentSan Francisco, Ca, UsConduct on-site acoustical field-testing in accordance with industry standards and practices. Test Sound Transmission Class (STC) of partitions and ceiling/floor assemblies, Impact Insulation Class (IIC) of ceiling/floor assemblies, reverberation time (RT60) and absorption characteristics of interior spaces, environmental noise levels (LDN/CNEL), groundborne vibration levels, suspended floor vibration levels, etc.Predict noise levels transmitted into interior spaces. Calculate airborne transmission of environmental noise through building envelopes, airborne transmission of interior noise through partitions, structureborne transmission of rooftop equipment noise through building framing, ductborne transmission of HVAC fan noise and turbulence-induced noise through building ductwork, etc.Predict levels of building floor vibration due to human activity, mechanical equipment, and excitation from environmental vibration sources. Calculate groundborne vibration impact of construction activities to nearby buildings, to prevent structural damage and interference with vibration-sensitive operations.Review project design drawings and documents to provide detailed recommendations and specifications to design teams, ensuring that project acoustical criteria are met within budget and without overdesign.Manage projects through tasks such as criterion generation, budget management, employee scheduling, resource coordination, billing management, and technical reporting. Manage projects ranging from small-scale (e.g. single rooms) to large-scale (e.g. full design and construction of multi-building campuses). Perform team-lead duties that include management of assignments, review of team member reports for submission to clients, and training of entry-level engineers in all aspects of the position. -
