What Sound Does a Car Make?

If it's a turbocharged (T) car, there are various sounds from the blow-off valve releasing air. For naturally aspirated engines, it's mostly the sound of the compressor releasing air. Here is additional information: 1. Blow-off Valve: Also known as a safety valve, it automatically opens and closes based on the system's working pressure, typically installed on equipment or pipelines of closed systems to protect system safety. 2. Function: The blow-off valve automatically opens when the safe pressure limit is reached, reducing pressure to ensure safety. The most common example is the pressure relief valve on a household pressure cooker, which is a simple mechanical release. There are also pressure relief valves in heating and air conditioning systems, which are water-floating type. Essentially, it's a valve that releases part of the pressure when the system exceeds the designed limit, allowing the system to operate normally.
My beloved car always growls like a waking beast when starting, especially during cold starts when the engine makes that chattering vibration sound, which turns into a steady hum as the RPM rises. The most thrilling part is during acceleration—the turbo kicking in sounds like a whistling whoosh mixed with the deep gurgle of the exhaust. The most annoying part is the squeaky screech of the brake discs on rainy days, like nails scraping on sheet metal. I remember when I first got the car, even the ticking sound of the turn signal was fascinating. The beeping alarm of the reverse radar in the old neighborhood drew curious glances from the neighbors. Over time, I’ve realized every car has its own unique soundtrack—mine always makes a squishy rubber sound when going over speed bumps.
