### How do sound waves work that make certain intervals sound good?

I'm learning waves in my physics class and I was wondering, how do sound waves work that make certain intervals sound good. Why does a M3/P4/P5 sound really good while m2/M2 sound (kind of) bad?

### Creating a Series of Repeating Pulses for Medical Alarms

I need to implement an audio alarm mp3/wav clip that contains a series of repeating pulses, where each pulse has to have a fundamental frequency somewhere between 150 to 1000 Hz, and there must be at ...
