Plantronics Acoustic Safety

White Paper

One example of Plantronics products feature SoundGuard Plus is Vista

M22 as shown at left. For

the full list of Plantronics products featuring SoundGuard Plus technology, see the product sheet at

the end of this paper.

SoundGuard Digital’s sophisticated algorithms provide additional acoustic protection above and

beyond the impulse and long duration disturbance protection that Sound Guard and SoundGuard

Plus provide. SoundGuard Digital constantly monitors signal levels, making subtle adjustments

when needed to prevent average daily noise exposure (TWA) from exceeding 85 dBA or 80 dBA

(per the user’s choice). Again, to ensure 100 percent compliance, and considering safety margin and

products and measurements variations, the actual acoustic safety limits of most Plantronics headset

products that contains SoundGuard Digital technology are well below the 85 dBA or 80 dBA limit.

SoundGuard Digital incorporates Plantronics’ anti-startle technology that not only guarantees

compliance to G616, noise level to be below 102 dBSPL at DRP both for impulse and continuous

noises, it detects and controls one, the delta between the previous listen level and the startle

noise level, two, the raising time of the startle noise, and three, the duration of the startle noise.

So SoundGuard Digital is designed to protect users’ hearing and improve listening comfort while

maintaining natural sounding speech.

One example of Plantronics products featuring SoundGuard Digital is the DA80 as shown at left.

Plantronics’ multimedia headset products that provide high-ﬁdelity stereo listening experiences,

including gaming headsets, are designed to meet IEC 62368-1, UL 62368-1 and EN 50332-1, -2 and

-3 PMP acoustic safety requirements.

All Plantronics’ multimedia and gaming headsets feature PMP acoustic safety technology. One

example is Backbeat Fit as shown at left. For the full list of Plantronics headsets featuring PMP

acoustic safety technology, see the product sheet at the end of this paper.
