The 1/f frequency fluctuation of quartz crystal resonators between liquid helium and room temperature is investigated in relation with acoustic attenuation. Large attenuation is observed at 50 K, due to ionic Na+ impurity relaxation, at 20 K, corresponding to the interaction of the sound wave with thermal phonons, and below 7 K, which is a behavior already reported in amorphous glasses. A strong correlation is found between 1/f noise level and acoustic attenuation around the phonon-phonon relaxation peak; this correlation is not observed on the Na+ impurity peak. Below 7 K, 1/f noise also increases in relation with losses. A possible physical mechanism for 1/f noise in quartz resonators is discussed.
