How to distinguish between high-frequency and low-frequency car horns?

[VonMakayla]

The unit responsible for reproducing high-frequency sounds, due to the higher frequencies, has a relatively thinner diaphragm to adapt to high-frequency vibrations. Responsible for reproducing low-frequency sounds, with larger and relatively slower vibration amplitudes, hence equipped with thicker paper cones and voice coils. The characteristic of high-frequency horns is the ability to vibrate quickly to produce sound, but their vibration amplitude is usually smaller. Their feature is having sufficiently large vibration amplitudes to push air and create high sound pressure (also known as sound pressure waves).
