We (and many others) used to run events in nightclubs and we built sound systems that reverberated everything in the room. It was impossible to not feel the rhythm as drinks shook off the bar if you didn't hang onto them. Everyone loved the vibe, but the coolest thing I noticed was that I made a lot of good friends from nearby Gallaudet University, who I didn't know were deaf until we spoke outside of the club... We slowly realized that Gallaudet students represented a rapidly increasing audience within events at the time as well because of the favorable party experience of deeper sound systems in comparison to other nightclubs, and specifically because of Drum & Bass Music's rhythmic depth.
They were able to read my lips flawlessly within the club at peak volume, and to differentiate songs literally based on the rhythmic patterns and bass reverberations they felt from the air pressure the sound system created on their skin... The connection is that hearing people actually went to the events for the same feeling, they just never realized the experience wasn't primarily about using our ears... It was truly an amazing time.
Many of the people I met and work with from that era are still good friends years later, and we always talk about how that vibe is missing from life now. Music is life.
