To better predict the sound generated by air terminal units, the AHRI variable air volume terminals certification program now requires air terminal unit manufacturers to include end reflection in their cataloged discharge sound power levels. When selecting units or comparing data among competitors, check the notes that accompany the performance data to ensure the data includes end reflection because the sound power levels and resulting NC calculated in AHRI Standard 885-2008 may be different if the data contains end reflection.
