Narrative:

Push back crews headset microphones do not filter engine noise; the engine noise at engine start during pushback is unbearable since they have a dave clark headsets and their microphone is uncovered; allowing the high pitch engine noise into our cockpit headset. It is impossible to hear the crew below asking to disconnect or give us any other piece of information. It is also a hazard to our hearing as it will impair and damage our hearing as we continue to start engines during push backs. Either provide the pushback crews with a closed mask microphone or delay engine starts until pushback crew is safely gone and out of the way.
