Choice acoustical products serve as a buffer against aircraft noise. Although the installed products do not soundproof the properties, they help restore an improved quality of life to our airport neighbors. Countless responses from satisfied participants indicate that the Residential Sound Insulation Program modifications have made a noticeable difference in their day-to-day comfort. Eligible properties within the RSIP noise contour, fifty years and older, may also qualify to be treated under the state's historical preservation guidelines. In this case, each home will receive acoustical modifications while maintaining its authentic value. Architectural plans are submitted to the Ohio Historic Preservation Office for a thorough review and approval. This added step lengthens the design stage, but it ensures all recommendations fulfill program standards and maintain historical integrity of the home.
