Soundscape study to develop a new noise ordinance

Abstract

A soundscape study was conducted to assist with the development of a new noise ordinance in the City of Delray Beach, Florida. Delray Beach has an active entertainment district, which is popular with tourists and locals. Integrated into the district and the surrounding area are recent residential and business developments. During the pandemic the entertainment district activity was reduced. Since 2021, the activity was resumed. With the intensified activity noise complaints to the City increased. The existing subjective noise ordinance was not effective. A soundscape study was conducted to determine the existing conditions, and to develop new data-driven, perception-based objective standards. The goals for the new ordinance were to create certainty for stakeholders, to balance the interests of businesses and residents, to manage expectations, and to ensure fairness and consistency in application. Long-term and short-term acoustical measurements were made, several public workshops and hearings were held and two soundwalks were conducted. The results of data collection are discussed. At the time of this writing, the draft of the new ordinance is in process, to be presented to the City Commission for consideration. The outcome of this effort will be presented.
