As it comes closer to you, the pitch gets higher, then gradually lowers as it passes you.
:-)
The pitch of the horn decreases as it moves away from you because of the Doppler effect. The sound waves get stretched out, causing the frequency and pitch to decrease.
The car's horn doesn't change pitch. As you pass by the Doppler Effect happens. The sound waves get increasingly loud then fade away and become increasingly quiet.
Decrease.
You will first notice the sound of the horn getting louder as the train approaches, then as it passes, you will feel a rush of wind and hear a loud noise as it speeds by. The train may also create vibrations in the ground as it passes.
Palindrome for blowing horn: 'toot'.
Parp, beep, toot or blast.
A palindrome for blowing a horn could be: 'toot'.
The change in pitch of a train's horn as it passes while you are standing still can be explained by the Doppler Effect. Just as any other horn or fast moving sound, When a object emitting loud sound is coming towards you, the sound is compressed and sounds like a higher pitch. When the object is moving away the sound is expanded sounding like a lower pitch.
On brass instruments in general, you speed up the air you are blowing through it and the pitch gets higher. Or in other words, the faster you lips vibrate, the higher the note.
