When the length of the straw changes the sound or pitch changes. Pitch is how high or low a sound is perceived. ... The longer the straw the lower the pitch – the shorter the straw the higher the pitch.
What causes the production of sound in the experiment straw flute?
In the straw flute, what's vibrating? The air inside each straw. When you blow across the top of your straw flute, you cause the air inside each straw to vibrate as it moves around. That movement of air is what we hear as sound.
How do you describe the sounds made by blowing the plastic straw?
When the reed vibrates at just the right frequency, the air in the straw vibrates powerfully, and you hear a loud, buzzing note, sort of like an oboe. When you blow through the straw, there is a high pressure in your mouth. ... The sound from your straw oboe is an example of a phenomenon called resonance.
Which straw produces louder sound?
The higher the frequency, the higher the perceived pitch. The shorter straw should have made a sound wave with a higher frequency than the longer straw, and so the shorter straw should have made a higher pitch than the longer straw.
