Yealink Acoustic Shield

Yealink Acoustic Shield is an innovative technology that greatly reduces background noise.

Here’s how it works.

The microphones of the phone’s handset pick up sound, both the speaker and the background noise. 

The phone then intelligently processes out more distant noise. In essence, it sets a virtual perimeter around the conversation, as if it’s taking place in a separate room.

The name of the technology describes the effect: Acoustic Shield.

Acoustic Shield Settings

The admin can configure Acoustic Shield to determine if and how it operates:

• Disabled
• Enabled — Enables manual activation of Acoustic Shield by tapping Acoustic Shield softkey on phone during call
• Auto — Automatically enables Acoustic Shield when call is initiated

The admin can also configure how strong Acoustic Shield acts from 1 to 3, 3 being the strongest.

When Acoustic Shield is set to 3, it will block out noise beyond 20cm (7.9”), which can be very useful for a desk phone in the open office.
