The different sounds:

A practitioner who is able to stimulate his kundalini inmeditation and cause it to rise up his spine to the point where it can engage and activate one of his cakras will hear the astralsound that is consistent with a particular cakra.

1. Awakening the muladhdra cakra will produce soundsthat resemble the chirping of birds or the buzzing of bees.
2. Awakening the svadisthana cakra will occasion soundslike the tinkling of bells.
3. Awakening the manipura cakra will elicit a ringingsound.
4. Activating the anahata cakra will produce sounds thatresemble the mellow tones of a flute.
5. And finally, awakening the visuddha cakra will giverise to sounds like the uniform reverberation of a drum or therhythmic cords of the AUM mantra.If these astral sounds are heard calmly they will lull themind into a tranquil state, and if meditation is continued, theywill fade naturally and disappear in a short time

Might be ear wax.
