NOISE

Noise testing is conducted to determine if materials can withstand external noises generated by various sources. It also includes air-borne and structure-borne noise measurements.

ACOUSTIC NOISE
The test is performed to demonstrate the adequacy of material to resist the external acoustic environment in which it is installed without degradation of its functional performance and structural integrity.

Acoustic noise testing is specified in the following:

MIL-STD-810, MIL-S-3928, MIL-F-7872, MIL-A-8064, MIL-F-8615, MIL-A-8870, MIL-T-15514, MIL-F-16377, MIL-I-11867, MIL-F-16377, MIL-T-17293, MIL-T-17301, MIL-V-17639, MIL-P-17869, MIL-P-18472, MIL-F-18870, MIL-F-19004, MIL-C-19113, MIL-C-23200, MIL-V-24509, MIL-F-24755, MIL-T-28800, ASTM C423-66, ANSI S1.26-1978, ANSI S1.31-1980, ANSI S1.32-1980, ANSI S1.33-1980, ASTM C423-66

AIR-BORNE NOISE
This test measures the acoustic air-borne noise generated by the test item.

Air-borne noise testing is specified in the following:

MIL-STD-740, MIL-I-983, MIL-STD-2036, MIL-P-15736, MIL-P-16097, MIL-F-16377, MIL-E-16400, MIL-M-17059, MIL-M-17060, MIL-T-17293, MIL-T-17301, MIL-V-17639, MIL-P-17840, MIL-P-17869, MIL-P-18472, MIL-F-19004, MIL-M-19097, MIL-C-19113, MIL-N-19900, MIL-M-19633, MIL-M-19160, MIL-C-23200, MIL-L-23886, MIL-C-24095, MIL-P-24423, MIL-F-2475

STRUCTURE-BORNE NOISE
The test measures structure-borne noise generated by the equipment under test. Structure-borne noise is self-induced vibration which is transmitted through equipment and ultimately into mountings and foundations.

Structure-borne noise testing is specified in the following:

MIL-STD-740, MIL-I-983, MIL-STD-2036, MIL-P-15736, MIL-E-16400, MIL-P-16097, MIL-F-16377, MIL-M-17060, MIL-T-17293, MIL-T-17301, MIL-V-17639, MIL-P-17840, MIL-P-17869, MIL-P-18472, MIL-F-19004, MIL-M-19097, MIL-C-19113, MIL-C-23200, MIL-L-23886, MIL-C-24095, MIL-P-24423, MIL-F-24755
