I like the descriptions and the sounds that happened afterward, but the arrival of the ambulances confused me. Isn’t he already at the hospital? Or am I missing something?

Sure… but ambulance always have a destination right?? Where is that? The hospital.
So it’s the sound of the sirens as the ambulances OUTSIDE arrive… May have to edit and make that more clear…

I see where it was confusing.

made the edit… see if that’s better Stovo!

Okay. I was still thinking of it as the ambulances arriving to pick Harold up and take him to the hospital, and in the middle of all the machines and other obvious hospital noises it confused me.

I got the ambulance reference, but I spent a lot of time in hospitals. Great job getting across the overwhelming nature of it all, his entry into the world of sound.

yes, the world with sound is overwhelming! you’ve captured it well, and without the learned filters we use for sounds, focusing on one above the others, each sound is a cacophony to him!
