Why Performance Matters?

Poor microphones cause muffled speech, repeated clarifications, longer call times, and more customer complaints.  Clear audio directly improves professionalism and customer experience.

Our Technical Advantage

Inbertec uses microphones with precisely tuned -47±3dB sensitivity to capture clear voice without picking up excess noise.

They are paired with cardioid unidirectional microphones, it focuses on your voice while rejecting side and rear background noise.

Sensitivity is typically expressed in negative values:the smaller the absolute value, the higher the sensitivity.

A value of -47±3dB means the microphone has sufficient pickup capability for normal speech and even quiet whispers from a seated speaker, while capturing subtle vocal details effectively.

If sensitivity is too high (e.g., -38dB), it can pick up quieter sounds but will also capture more ambient noise, keyboard clicks, and breathing.

This places extra burden on noise-canceling algorithms and may actually reduce speech clarity if not properly managed.

Common types:

• Omnidirectional

• Cardioid (Unidirectional)

Call centers prefer cardioid microphones because they mainly capture sound from the front (directly in front of the agent’s mouth) while effectively rejecting noise from the sides and rear.

This polar pattern is a core technology for ensuring clear voice transmission.

Inbertec Professional Audio Solution

In the call center industry, clear communication is just as important as noise reduction.

As a professional headset manufacturer, Inbertec headsets use unidirectional noise-canceling microphones with precisely tuned sensitivity of -47±3dB.

They accurately capture vocal details while effectively suppressing environmental noise.

Inbertec ensures clear, efficient communication at the source, providing reliable audio solutions for professional call center environments.
