When I first got my hybrid, I had read it has a "soundaktor" function when in the sport mode, which adds internal cabin noise to make the engine sound beefier than the tiny 1.4L it really is.

I thought I'd hate it and disconnect the wiring harness by the next day, but I actually quite like it.

It's weird.  Psychologically we expect noise from a vehicle travelling fast.  I do like the silent acceleration in electric mode, but I also don't hate the noise inside the cabin, under slightly sporty driving conditions.

Maybe it'll get boring eventually.  My next car will almost certainly not have it as a function.

Why would you like to have extra noise in the cabin? To me the idea is insane. Sound doesn't make a car go faster.  My previous car had a rather loud diesel engine. I installed over 25 sqm of thick, sound proofing rubber mats in it to lower the noise a bit. I took the entire interior + lining out and put the rubber mats underneath.

Wallace Gasiewicz:
In the past there were complaints of steam vehicles being too quiet and then in the 60's the Chrysler turbine sounded like a "Vacuum Cleaner"

When we were developing electric vehicles at GM in the 1980's the safety concern of a quiet vehicle was also addressed as a problem.

Why do motorcyclists insist on loud noise from their machines?  It's a matter of taste.
However,  there are regulations requiring audible sounds outside the vehicle to warn pedestrians of its approach.
US regulation for hybrid and electric vehicles (2022): 

"To protect pedestrians and other road users, FMVSS No. 141 requires HEVs to emit a pedestrian alert sound while operating in certain conditions.
The alert sound on a given vehicle is allowed to change with vehicle operating speed or direction—the standard defines five different operating conditions: stationary in neutral or forward gear and with constant forward speed less than 10 km/h; reverse; and moving at constant forward speed from 10 km/h up to but not including 20 km/h, from 20 km/h up to 30 km/h, and at or just above 30 km/h. Beyond that speed, alert sounds are no longer required by FMVSS No. 141 as other sounds such as tires and airflow produce enough sound to make the vehicle detectable."

I (used to) use engine noise subliminally as a speedometer, particularly to detect small changes in speed.

In another vehicle I've used, the air noise was the equivalent of the constant beeps from radiation monitors in Sellafield nuclear reprocessing plant. If either disappear, you rapidly become very alert and find out why :)
