The phonautograph is the earliest known device for recording sound. Invented by Frenchman Léon Scott, it was patented on March 25, 1857.
In a tape recorder, electrical energy from the battery is transformed into sound energy by converting the electrical signal into mechanical vibrations in the speaker, which produce sound waves. The sound waves then propagate through the air as sound energy that we hear.
a sound level meter ( it measures in dB)
A recorder works by using a mouthpiece to blow air into the instrument, which vibrates a reed or fipple. The vibrating air creates sound waves that travel through the recorder's body, producing music. The key components of a recorder include the mouthpiece, the body with finger holes, and the foot joint with keys for playing different notes.
A small recorder (such as a treble) - has a smaller slot where the sound is produced. This makes the instrument produce higher note than in a tenor recorder - which has a larger slot producing lower notes.
The first man-made object to move faster than the speed of sound was the Bell X-1 aircraft, piloted by Chuck Yeager on October 14, 1947. It broke the sound barrier and reached a speed of Mach 1.06.
