All vacuum cleaner reviews on Modern Castle are put through our standard noise test.

The feel of the steering wheel is better than that of Michelin and Goodyear.

A noise measurement test system is provided for making phase noise measurements of a unit under test (UUT).

If a test for noise sensitivity is successful with this injected worst noise, then the system is accepted.

A noise interval analysis unit (230), on the basis of results of the checking of each test frame (190), calculates noise intervals at which noise occurs.

The automatic hearing test also detects and compensates for ambient noise in the test results.

The noise source (500) transmits noise at the total noise power from the at least two antenna elements (102 to 116) to the device under test (100) wirelessly.

A reference model of fixed pattern noise is associated with the test image.

In this way high current switching noise can be eliminated during testing.

The testing modem (4) is used to test the signal quality of the network, such as by using a SNR test.

Examples: testing of engine noise reduction solutions, endurance testing of innovative materials

A test apparatus and method for a noise reduction earphone.

The automatic hearing test also detects ambient noise and can compensate for it in the test results.

In the case where the worst noise test fails, the method consists in calculating by simulating the lowest-level noise observed in said system, or the injected best noise.

Standardization of a test of speech perception in noise.
