Drive Acoustic Silencer is a software utility for laptop computers created by the Toshiba Corporation to lessen vibration noises produced by optical CD and DVD read-only memory (ROM) drives. Optical CD and DVD drives sometimes emit noticeable vibration noises when reading or writing to discs at high speeds; the Drive Acoustic Silencer program reduces those read/write speeds to limit external noise.

Main Causes of Disc Drive Noise

CD and DVD drives normally produce the most noise when performing tasks that cause the disc inside to spin at higher than average speeds. Tasks like burning CDs and DVDs, extracting large amounts of data or ripping multimedia files, such as music from a CD or DVD to the hard drive, require higher read/write speeds to process quickly. These higher speeds require the disc inside the drive to spin faster, increasing the level of noise the drive makes.


Since Drive Acoustic Silencer works by limiting the maximum read/write speeds a disc drive is able to use, it is most useful for reducing noise emitted during more demanding processes like ripping or burning discs. Excessive noise from simply listening to music from a CD or watching a DVD is less common and could indicate a different source of the noise problem entirely.

Other Causes of Drive Noise

Any hardware defect that interferes with the proper mounting and alignment of a disc can cause a noisy disc drive. Such hardware defects are common and include bent discs, discs with cracked or dirty centre holes, drives with damaged clamping mechanisms and even tiny bubbles under the surface of a disc's label.


Note that Drive Acoustic Silencer software can reduce sound output from normal disc drive use; however, it cannot limit noise caused by other hardware issues. If a physical defect in a disc or the drive itself is causing a misalignment, limiting the read/write speed of the disc will not help prevent any excess noise.


Drive Acoustic Silencer is a small program that uses very little memory, making it easy to run even on older notebook computers with limited system resources. It is simple to install and is available for free on the Toshiba support website. To install Drive Acoustic Silencer, select the appropriate version for your operating system and download the .exe file. Run the installer and follow its directions. Then reboot at the end if prompted.
