After many years of private lectureship, he was appointed professor at the TH Breslau in 1920, was its rector from 1930–1932 and from 1926 to 1938 director of the physics institute at the same university. In 1935 he was elected a corresponding member of the Göttingen Academy of Sciences .

Waetzmann worked on several areas of acoustics . After working on questions of physiological acoustics and combination tones, he and his student Kurt Schuster published in 1929 a wave-theoretical derivation of the Sabine reverberation formula empirically found in 1900 .
