Noisy Or Quiet: From 38 To 73 DB(A). a comparison of 34 coolers for the amd athlon xp. The noise level of the tested fans varies according to the model, from an extremely quiet, barely audible 38 dB(A) (which can be compared to a loud whisper) up to an annoying 67 dB(A) (loud talking). To compare the noise of the fans, you should go by the following rules of thumb: twice the volume is equivalent to an increase in the noise level of 10 dB(A); four times the volume is therefore equivalent to an increase in the noise level of 20 dB(A); differences of 1 dB are virtually inaudible, while differences of 3 dB(A) are clearly noticeable....

Here are the corresponding graphs: Bandwidth Reponse 20 Hz to 20 kHz, dB -0.25, +0.04 40 Hz to 15 kHz, dB -0.02, +0.01 The card's bandwidth curve shows whether its frequency reproduction over the entire sound spectrum is balanced. Parameter Left Right RMS Power, dB: -78.6 -80.1 RMS Power (A-weighted), dB: -80.4 -82.0 Peak level, dB FS: -67.6 -68.3 DC offset, %: -0.00 -0.00 The second test is of noise and interference levels, and measures in particular where the card's background noise is located and its sensitivity to interference from the computing environment: power supply, transformers and monitors. Parameter Left Right Dynamic range, dB: +76.1 +77.7 Dynamic range (A-weighted), dB: +78.0 +79.5 DC offset, %: -0.00 -0.00 Related to the above test, the dynamic range test gauges the level of noise generated in the presence of a sound signal, in this instance a sine wave (1 kHz at -60dB) at card input. It assesses the card's sound fidelity, noting the appearance of harmonics when a single but high (-3 dB) sine wave is sent to the card. Parameter Left Right IMD + Noise, %: 0.046 0.040 IMD + Noise (A-weighted), %: 0.039 0.034 Parameter G <- D G -> D Crosstalk at 100 Hz, dB: -76 -77 Crosstalk at 1 kHz, dB: -80 -80 Crosstalk at 10 kHz, dB: -65 -65 ...
