Hi David,
I think that so wonderful that you have had a life long love of museums. I believe you bring up a very interesting point with many diverse answers. Several museum professionals have already responded to you stating that there are plenty of aesthetic reasons for there to be a loud auditory component to an exhibit. I also wanted to point out that museums cater to visitors with a variety of differing abilities. An audio component may be intended as an aid for people who cannot read, people who have low vision, people who are blind, or youngsters that haven't learned how to read yet.
However, theses auditory components can create uncomfortable sensory experiences for other guests who may be more sensitive to light, sound, etc. Many museums offer special timed events where exhibit components have been turned down or otherwise altered to create a calmer, quieter museum atmosphere. These events are usually called "sensory friendly". My museum The Franklin Institute, has held two "Sensory Friendly Sundays" which were successfully received by audiences who are sensory sensitive and/or enjoy a calmer museum experience. I would recommend contacting your favorite museums and asking if they offer this type of programming.
I hope that I helped to answer your question.
If you have any more questions about these type of events feel free to contact me. I would be more than happy to help.
Thank you for your ongoing museum patronage,
Becky
