Narrative:

Frequency change was made from 1 high sector to another. The new controller was female and the tone and modulation of her voice blended with many outside noises coupled with a high degree of backgnd noise from ZFW. Both pilots were monitoring the frequency. Female controller said she called us numerous times without any acknowledgement. Both myself and first officer never heard a single call made to us. We were monitoring all the transmissions she was making to other aircraft. To my knowledge, there was no traffic conflict. The communication problem resulted in a late handoff to the low sector and approach control. The use of a noise suppressor in this instance probably would have solved the problem.

Title: ACR MLG MISSED SEVERAL CALLS FROM ARTCC RESULTING IN LATE FREQ CHANGE HDOF.

Narrative: FREQ CHANGE WAS MADE FROM 1 HIGH SECTOR TO ANOTHER. THE NEW CTLR WAS FEMALE AND THE TONE AND MODULATION OF HER VOICE BLENDED WITH MANY OUTSIDE NOISES COUPLED WITH A HIGH DEG OF BACKGND NOISE FROM ZFW. BOTH PLTS WERE MONITORING THE FREQ. FEMALE CTLR SAID SHE CALLED US NUMEROUS TIMES WITHOUT ANY ACKNOWLEDGEMENT. BOTH MYSELF AND FO NEVER HEARD A SINGLE CALL MADE TO US. WE WERE MONITORING ALL THE TRANSMISSIONS SHE WAS MAKING TO OTHER ACFT. TO MY KNOWLEDGE, THERE WAS NO TFC CONFLICT. THE COM PROBLEM RESULTED IN A LATE HDOF TO THE LOW SECTOR AND APCH CTL. THE USE OF A NOISE SUPPRESSOR IN THIS INSTANCE PROBABLY WOULD HAVE SOLVED THE PROBLEM.
