- John Sandvig, Acoustical Consultant
Holland Home contacted ABD Engineering and Design to address concerns from the residents regarding the HVAC noise in the courtyard. ABD provided acoustical measurements of the equipment, and took ambient noise measurements inside residences. Mitigation recommendations were described in our report to reduce the noise. Following construction of the prescribed enclosures and other measures, ABD was invited back to take follow up measurements, to show the reduction in mechanical systems noise.
