If you play a note of a certain frequency on a flute and simultaneously sing a note at a different frequency, then you create a third frequency that wouldn't be there if you play or sing in isolation - and the frequency of this subharmonic is the difference of the flute frequency and the voice...

Similar to Flight and Power plant training simulation softwares, is it possible to design and develop musical instruments training software simulators? Examples : Guitar,Piano,Violin,Trumpet, Drums,Saxophone etc. If Not, What are the challenges for designing and developing Musical instruments...

What's the reason why beats sound pleasing to ears? It looks like the tones that beat with each other a lot more in general sound pleasing.

Hi people, So I've been digging into music theory and want to understand the basic reasons for how it is constructed. I've come across a particular relationship but I can't understand the reason it exists. A quick musical lesson: Imagine you've got a pure musical note: let's say C. From a low...

Hi there, I am a guitarist and have recently decided to learn the piano as a tool for learning music theory. In digging into music theory I've come into wanting to understand it from the very physics of sound upwards. You'll probably find me on forums discussing sounds theory mostly! I live in...

Homework Statement A stereo amplifier is rated at 130W output at 1150Hz. The power output drops by 10.0dB at 15.3kHz. What is the power output in watts at 15.3kHz? Homework Equations R=I/Io Io = 10^-12 w/m2 bel = log(r) The Attempt at a Solution I have no idea where to start

Homework Statement The A string on a violin has a fundamental frequency of 440Hz. The length of the vibrating portion is 32.4cm and has a mass of 0.340g. Under what tension must the string be placed? Homework Equations V = Fλ Vs = √t/μ The Attempt at a Solution I plugged in my info to...

Homework Statement I have a mass of 100 g and I want to make it oscillate with a period of 10 Hz. What spring stiffness do I need? Homework Equations f = 1/2π√s/m The Attempt at a Solution I don't know how to find the stiffness to plug into the equation.

Homework Statement Suppose a string is 0.50 m long, it has a mass per unit length of 1.2 g/m, and it is under a tension of 52 N. What is the frequency of the second mode of this string? Express your answer in the SI unit for frequency? Homework Equations f = Vs/2L Vs = sqrt (F/μ) The Attempt...

Homework Statement This is a homely. We were instructed to make a monochord and find and mark C5, G4, F4, E4, D4 & C4 by multiplying our starting length with the length rations (C5 = 1/2, G4 = 2/3, F4 = 3/4, E4 = 4/5, D4 = 8/9, C4 = 1) Then we used "Ravenlite" the application to measure the...

Homework Statement Suppose we listen to the sound of a vibrating string with a pickup that is sensitive to the motion at a point 1/3 of the string's length from one end. Which statement is true? A.) We will be able to hear all of the modes except the third B.) We will not be able to hear the...

Homework Statement Suppose a harp string is tuned to middle C (C4) and is 0.56m long. If I want the tension to be 193.5 N, what mass per unit length do I need the harp string to be? Calculate your answer in kg.m Homework Equations Vs = sqrt(T/μ) V = fλ The Attempt at a Solution Having a very...

Does anyone know how to solve this question? The atmospheric pressure is 0.850 atm. The rarefactions of a particular sound wave then reduce the pressure to 0.841 atm, what is the amplitude of the pressure wave expressed in metric units N/m2(squared)?
