Generally that metallic sound is really coming from your front disc brake sensors, they make a squealing sound when they wear down to a certain thickness of the brake pads allowing a small metal bracket called a brake sensor to rub upon the disc brake rotor in order to aleert the driver its time for the brake pads to be relined. Other things may be belt noise under the hood(loose, worn, etc.) or a pulley(idler/adjuster pulley with worn out bearings) bad alternator bearings, water pump or anything that may have loosened up and is hitting the moving parts in the front of the engine.
It makes a dull sound, while a metal makes a ringing noise like a gong!
Music because music makes a pitch sound 🔊 🎶
higher in pitch, due to the Doppler effect. As the car approaches, the sound waves are compressed, making the pitch sound higher to the listener.
A higher amplitude or greater energy in sound waves makes pitch louder. The intensity or volume of the sound wave determines its loudness.
Lower sound
the bigger an instrument is, the lower the sound that it makes
The sound a whistle makes is often described as "whoo" or "wee" depending on the pitch and intensity of the sound.
The sound a metal makes can vary depending on its type, thickness, and how it's struck or manipulated. Generally, metals produce a sharp, resonant ringing or clanging sound when hit, often described as a "ping" or "clang." This sound is characterized by a clear, sustained tone that can carry over distances, especially in materials like steel or brass. Additionally, the pitch and quality of the sound can change based on the shape and size of the metal object.
The pitch of a sound is determined by its frequency. A higher frequency produces a higher pitch, while a lower frequency produces a lower pitch. The faster the vibrations in the sound wave, the higher the pitch will be.

When a bell is struck, it creates vibrations within the metal that travel through the air as sound waves. These sound waves reach our ears, and our brains interpret them as the sound of the bell ringing. The pitch and volume of the sound are determined by the frequency and amplitude of the vibrations.
It vibrates to the pitch it is tuned to.
