Well 30 dB hearing loss means mild hearing loss. You need to check whether it's Conductive or Sensorineural hearing loss.
If it's Conductive Hearing loss then probably it's due to infection and secretion gone via nose to middle ear via Eustachian tube leading to Serous otitis media.
If it's Sensorineural neural hearing loss then it's due to viral infection which effected auditory nerve or inner ear.
