With most new hearing aids users, multiple tunings are required as they cannot handle the new volume and intensity of sounds that hey haven't heard for years.
An audiologist will typically test someone, see that they need amplications across the range but send them away with a much lower amplification for a weeks to get used to things. Then bring the volume up as time goes by.
People amy also need to get used to the aid's noise reduction algorithms as they can seem unatural at first and is a nightmare for anyone who used to wear an old analog hearing aid with no noise reduction.
So, yeah, hearing aids are rarely plug-and-play from day one - the user needs time to adjust.
