In addition, The American National Standard Institute (ANSI) and the Acoustical Society of America (ASA) give suggested limits for low -frequency unweighted sound pressure levels to avoid perceptible vibration and rattles at receiving structures in the standard ANSI/ASA S12.2 -2008. Table 1-3. presents those limits. Table 1-3. ANSI Low 260 Specifications 23. Technical Data XL2. All specifications are according to the IEC61672 standard.

Balanced Noise Criterion [NCB]: The new Balanced Noise Criterion curves, updated in ANSI S12.2-2008, accounts for sound frequencies down to 16 Hz, which will address issues from the low-frequency hum of energy efficient HVAC equipment. NCB also reduces the higher frequency levels to eliminate hiss. on Proposed ANSI S 12.13 Outcomes for Characterizing Hearing Conservation Program Effectiveness Thomas H.

International standards organizations (ISO, ANSI and ASA) recognize the need to objectify judgements on the amount of ambient noise in enclosed spaces, and provide us with definitions for various noise curves. The ANSI/ASA S12.2-2008 standard, for example, recommends an NC value of 25-35 for schools and 15-18 for concert halls.
