Noise Estimation Framework for Advanced Air Mobility

Speaker: Joseph Czech, Principal Consultant, Harris Miller Miller & Hanson Inc. Abstract: Community acceptance and adoption has been identified as a critical and challenging component as we prepare our communities for Advanced Air Mobility (AAM) operations. Although AAM vehicles may be significantly quieter than traditional rotorcraft, the proposed scale of operations and proximity to the built environment makes noise generated from AAM operations a concerning element. Therefore, it is essential to incorporate noise estimation in the planning stage. The presented analysis demonstrates a noise estimation framework for AAM operations. The framework utilizes simulation models and the current state of knowledge combined with laboratory data to inform the modeled sound sources. This framework is part of the Advanced Air Mobility – Community Integration Planning Tool. The noise estimation framework takes trajectories of proposed AAM operations and simulates them with the Advanced Acoustic Model to compute their noise exposure. Combined with demographics, the results can assess the potential for noise impact of the proposed operations. The framework is developed to provide quick and credible noise results with the ability to vary temporal and spatial granularity while accommodating different types of vehicles. The paper involves proposed multiple AAM cargo operations in the Midwest region of the United States. Bio: Joseph Czech is a principal consultant at Harris Miller Miller & Hanson Inc. (HMMH) since 2016 and has more than 34 years in the acoustical consulting field, with experience conducting noise and/or environmental studies ranging in value from less than $10k up to $12M for a variety of military and civilian clients. His expertise is in modeling aircraft noise, measurement, project management, research, public meetings, and litigation support. Czech is an expert in the use of the NOISEMAP suite (including MR_NMAP and the Advanced Acoustics Model) and helped develop AEDT. Besides subsonic aircraft, his projects have addressed the noise from road traffic (TNM), construction, blast/ordnance (BNOISE2), small arms (SARNM), (low- and high-speed rail, light rail, busway, electrical substations, and sonic booms.
