The LMV1099 is an uplink and downlink voice intelligibility enhancing analog IC, ideally suited for mobile handsets. Uplink voice intelligibility is improved by rejecting far-field noise through a unique two-microphone solution. Downlink voice intelligibility is improved by enhancing the SNR (Signal-to-Noise Ratio) between the downlink voice and the ambient noise environment at the user’s earpiece.
The LMV1099 preserves uplink near-field voice signals within close range of the microphones while rejecting far-field acoustic noise greater than 0.5m from the microphones.
The LMV1099 also enhances downlink voice intelligibility by improving near-field SNR based on the user’s environment
