Typical Wavelengths
Some typical wavelengths for midfrequency octave centers are shown in Table 3.2. Now suppose the temperature increases 20°F to 92.5°F.
Suppose we had “tuned” to the peak of a 1000-Hz standing wave in a room first at 72.5°F and then later at 92.5°F. The apparent frequency shift would be
where 1151 is the velocity (ft/s) at the temperature of measurement and 1.13 is the wavelength at the original temperature.
