logo.gif Examples of Noise Suppression in CD-ROM Drives


Noise Emission Status

Noise from both the CD-ROM drive and computer are conducted through the headphone cable and radiated.

Since an internal CD-ROM drive is shielded with a metal case, radiated noise from the CD-ROM drive rarely causes a problem. However, in some cases, radiated noise from the headphone cable can cause problems.
