I have a Panasonic DECT 6.0-Series 3-Handset Cordless Phone System with Answering System (Model KX-TG1033S) which includes 1 base unit, 3 handsets and 2 chargers. All of the handsets have NEW Panasonic NiMH 700mah AAA Rechargeable Batteries.

When the phone rings, a buzzing sound emanates from the handsets. (The caller does not hear the buzzing sound).

How can I eliminate the buzzing sounds?

Do you have a wireless router? You might try turning that off to see if it's interference from it. What's the frequency of your phone system? Sometimes WiFi routers interfere with cordless phones. ?(?)?

Panasonic DECT is generally 5.8ghz and does not interfere with or get
interference from wifi or bluetooth. I gave 3 Panasonic DECT phones
and have never had any problem with noise (except for BAD line noise).
A previous set I had got noisy so I threw it away and got the DECT
set. On mine it appeared to be a base station problem as it affected
all phones connected to it.

First thing I would do is connect as standard wired phone to the
system and see if it is noisy too - we did have a cabling problem with
Bell so I switched to OOMA and now I don't have the line noise issue.
