A-WEIGHTED SOUND LEVEL. An A-weighted sound level is a sound level occurring in the1,000 to 6,000 Hz frequency range that is increased by 10 dB if the noise event occurs between10:00 p.m. and 7:00 a.m. The A-weighted sound level reflects the greater intrusiveness of soundsthat the ear perceives as louder compared to other frequencies. “dBA” or “dB(A)” indicate asound level measurement has been A-weighted.

DAY-NIGHT AVERAGE SOUND LEVEL. The day-night average sound level is the noiseexposure in areas around airports (abbreviated as “DNL” in text and “Ld” in equations). DNL isa measure of the average A-weighted sound level of all aircraft flights occurring in a 24-hourperiod.

324.2 Aircraft noise zone. All land within a DNL noise contour of 65 dBA or greater, as shownon the aircraft noise maps available for review at the Division of Building Inspection is subject tothese regulations. A building that is only partly located within an aircraft noise zone is alsosubject to these regulations.

324.3 Noise insulation.

324.3.1 Certification of plans prior to issuance of building permit. A registered Texasengineer who has demonstrable knowledge of acoustical engineering shall certify that theplans and specifications comply with the noise insulation standards of Section 324.3.2. Thebuilding official shall not issue a building permit for any building within an aircraft noisezone unless the plans and specifications for thc building meet the noise insulation standardsof Section 324.3.2.

Exception: The plans and specifications may be prepared and certified by a member ofthe National Council of Acoustical Consultants or another organization approved by thebuilding official

324,3.2 Noise insulation standards. New buildings must be constructed with soundinsulation or other means to achieve a DNL of 45 dBA or less inside the building. If the costof modifications to an existing building is 75 percent or more of the total assessedimprovement value of the site. the building must also meet this standard. Garages andsimilar accessory buildings that do not include living space are exempt from thisrequirement,”
