Pitch Definition and 119 Threads

Hello everyone. I'm not a Physics major: I'm a Music major. And I have a question. I've read various books on acoustics, but I still haven't found the answer. Ok. The way I see it, there are 2 basic types of sounds (I didn't get this out of a book, it's my own conclusion from everyday...

if the diametral pitch of the pinion is x, would the diametral pitch of the gear also be x?

Recently I attended a lecture related to the physics behind swing of cricket ball. But the speaker dealt with the swing before pitching(and dealt loosely with late swing). He took only the effects of air in consideration. I am interested to know how the pitch effects the swing(or seam movement)...

What causes the feedback (a noise increasing in intensity and pitch) sometimes heard when people speak through microphones? I'm sure I have enough background to understand an explanation, I've just never thought about it before.

Homework Statement One of the fastest recorded pitches in major-league baseball, thrown by Billy Wagner in 2003, was clocked at 101.0 mi/h (Fig. P3.22). If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically (in feet) by the time it reached home plate...

Does the decrease in atmospheric pressure with increasing altitude affect frequency of sound, such as that of a mountaineer's voice?

Homework Statement It's for a physics project, in which I'm trying to calculate the velocity applied to a fastball thrown at 95mph, when the bat speed of a hitter is 86.99mph. The weight of the ball is 5oz, the weight of the bat 31oz, and we'll go with contact on the ball at .005s.(This is...

I don't know which mentor to address this question to so I'm trying it here. After I have stirred my coffee I always tap the spoon on the lip of the cup. As I do so the pitch keeps rising until the coffee is no longer moving. I've been curious about this for years and hope somebody can answer...

Why are pitch and frequency similar to loudness and intensity? I also have one more question! I have a test coming up on the properties of sound things likethe spped of sound etc? Does anyone have like an old test or something i can use to help study?

Hi there Can someone please help me with this question I have no idea how to work it out... A tuning called 'philosophical pitch' has C4 (Middle C) at 256Hz. What is the difference in cents between notes at this pitch standard and those in modern concert pitch (A4 at 440Hz)? Thanks in...

Im curious about this question because of the TV's at school. I can hear a TV on in a house with extrenious noise even if the TV is muted. I asked my science teacher if she could hear the TV when it was on and she said she heard the sound but that's all. I hear a very high pitch noise when a TV...

EASY STUFF: Impedence, pitch, vibration, reasonance... Please Help! I would really appreciate it if you guys could take a look at these problems I have difficulty with. Thanks a lot. My answers are in red. 1. As impedance decreases, frequency decreases? 2. For the vibration spectrum (of...

Hi. I would really appreciate it if someone could tell me whether I'm correct or not. :smile: 1. An open pipe (open at both ends) and a closed pipe (closed at one end) are the same length. If an organ blows air across the top of each pipe, what is true of the frequency (and pitch) of the...

I was hoping that someone here would be able to help me understand variable pitch blade systems for fans/turbines and how they work I have already searched the internet quite a bit without much luck There are a few mechanical drawings but they leave a lot to the imagination Any help is...

As a clarinet student, i have always been told two things: 1.) to change your loudness, change the amount of air you send through the horn, not the speed at which you send air through it. if you change the speed, you will change the pitch. 1.) you can change your pitch by tightening or...

The big event of the softball season, the Women's College World Series, begins Thursday. One aspect I find interesting is that many of the dominant pitchers are very tall. Many of you are probably familiar with the underhand delivery of fastpitch softball, which implicates angular motion. The...

In a screw gauge, the pitch is defined as the distance traveled in one rotation. Is it also equal to the length of one main scale division? If the length of one main scale division is not given, then can we take it to be equal to the pitch? Or do we take it as equal to some other default value.

Hey , I I need to verify my work about this problem: Two small objects A and B are suspended from the ends of a rope thrown over a pulley. Object A is at 1.2 m above B when the system is at rest. Object A descends with a downward acceleration of 0.3m/s2 and because of the rope, B...

Hi all! I would like to know how, in workshop practice, one would measure the tooth thickness and pitch of a spur gear?
