I spent years living in Asia and I found the streets to be incredibly noisy. The main problem was two-stroke scooters. Not only are two-strokes inherently noisy, but users often remove the mufflers to improve the power (two-strokes hate back pressure). However in recent times there's been a big change to four-stroke and even electric scooters. Which means that the noise levels have improved somewhat. Still terrible though.
