High pitched noises sometimes. I have an audio spectrum visualizer app installed to confirm these. But they can be pretty weird as they bounce around. You’ll get these heat spots. Unfortunately, I feel like my ears are degrading now. Anyway, dimmable LED lights are often a problem due to PWM. Only full brightness is quiet. Smell, I don’t even know what the hell that was. There is or was something in the back of one bus. I wouldn’t say it’s smell, but… something. Just a spicy punch that doesn’t quite let me breathe in. I noted down the license plate if I’ll experience it again to confirm it’s the same vehicle, but this wasn’t the first time, though unfortunately I didn’t copy it that first time. Same line though, so possibly same vehicle as well. But I am not sure if I was the only one, no one was visibly bothered, but who knows.

That high pitch sound from lights and power packs drive me crazy. It’s so loud and high.

As someone who can’t hear high pitches at all, I do recognise this funky bouncing of frequencies at the edge of my hearing range (probably around 15 kHz, I haven’t precisely measured it). It’s surprisingly hard to locate sound sources when you only hear them when you’re facing a certain angle in a certain spot in the room! These are always too quiet for my phone to pick up, so that’s no help sadly I wonder if there’d be a market for a variant of a phone model that is just all-round decent, but has a better microphone and other sensor upgrades. I run into the sensor limits a lot (probably weekly) but also don’t want to permanently run around with a bulky sensor board in my pocket :<
