5. PHYSICS OF SOUND - Pennsylvania State University

Sound is usually caused by radiation from a solid vibrating surface or fluid disturbances. 5.1 ACOUSTIC VARIABLES As sound propagates through air (or any elastic medium), it causes measurable fluctuations in pressure, velocity, temperature and density. We can describe the physical state in terms of mean

Section V considers clustering when there is more than one way to do so and these ways are not nested in each other. Section VI considers how to adjust inference when there are just a few clusters as, without adjustment, test statistics based on the cluster-robust standard errors over-reject and confidence intervals are too narrow.
