# Pitch vs volume

difference between pitch and volume?if a sound is high pitched ,doesn't it mean that sound is loud?I don't think so because loudness is related with amplitude and pitch has to do with frequency,right?BUT please someone explain how can we say whether a sound is high pitched or loud just by listening ,what's the difference between pitch and volume?

I don't understand your question. As you said, we amplitude and frequency. Our ears can sense both.

I just want to ask difference between high pitched sound and loud sound?

No, it does not mean loud. Pitch and amplitude have nothing to do with each other.

yes, that's right.

Why is that a problem? You will hear a bomb going off a mile away will as a low-pitch boom, pretty soft. You will hear a bomb going off to you very close as low-pitched and LOUD. You will hear a police siren far away as a high-pitch sound, but quiet and you will hear a police siren right next to you as a high-pitched sound and LOUD.

why sound of bomb is low pitched?

Consider a violin or flute playing a high-pitched note. It can be either loud or soft, at the same pitch.

Likewise for a string bass or bassoon playing a low-pitched note. Same thing.

Or consider a piano. Hit a key at the left end of the keyboard twice, first gently, then hard. You get the same low pitch, first soft, then loud. Do the same thing with a key at the right end of the keyboard. Same thing, but at a higher pitch.

I don't even know how to answer that. Do you associate "BOOM" with a high pitch? I don't.

The high frequencies from a distant explosion are attenuated by the air more than the low frequencies are.

Higher frequency mean high pitch ? Directly

'Pitch' refers to the perception of whether a sound is high (e.g. a soprano) or low (e.g. a bass); it is related to the frequency of the sound wave. A high pitch sound has a high frequency, and a low pitch sound has a low frequency.
'Volume' refers to the perceived loudness of a sound, and this is related to the amplitude of the sound wave.
Perceived volume does depend on frequency as well as amplitude though; a sound of 1000Hz will sound louder than a sound of 100Hz having the same amplitude. This is because the sensitivity of our ears varies with frequency. (See http://en.wikipedia.org/wiki/Loudness for example.)

Instead of posting notes in a forum, may I suggest thst you spend some time listening to Ravel's Bolero.
There you will hear high pitches and low, in amplitudes from low to high in a very enjoyable way.

i would listen high pitches and low, in amplitudes from low to high but i won't be able to distinguish between them .And i just want to distinguish between them

Pitch is Frequency.
Volume is Amplitude is commonly referred to as Loudness.
Does anyone have a problem with that (anyone with relatively normal hearing, at least). Is this a language thing, possibly?

loudness i.e high volume i know but what is high pitched sound?

15. Dec 5, 2014

### sophiecentaur

High Pitch = High FREQUENCY
= Many cycles of oscillation per second - as with the notes at the extreme right hand side of a Piano.
Have you considered looking in a dictionary?

16. Dec 5, 2014

### gracy

Thats the thing (advice) i think would help me .otherwise High Pitch = High FREQUENCY
= Many cycles of oscillation per second
the definition i already knew.I just want to listen high pitched sound.

Then have a small girl scream in your ear. That way you can get high pitch and loud at the same time

hmmm......... so shrill sound means high pitched sound.

It's a pity you didn't read Post 6 properly. It would have saved us a lot of time and frustration. If you weren't familiar with the instruments quoted in that post then Google would have given you a way to hear samples of them.

As long as you don't waste your time, you haven't wasted anyones. :)

It seems that the core of the problem is that you're not actually sure what quality pitch refers to. It has nothing to do with how loud the sound is, but where on the scale of frequency it is.

Surely you are familiar with a piano.
The notes played on the left of the keyboard (C1-C3) we hear as low-pitched.
The notes played on the right of the keyboard (C5-C8) we hear as high-pitched.

I don't think i have wasted my time as I was just trying to clear my doubt no matter how long it takes the only thing matters to me to get the point i am curious or confused about.That's what i got .SO for me it was the best use of time,but i am not sure about others,that's why i said sorry.
