Final answer:
The cause of postnatal hearing loss can be attributed to genetic factors, noise exposure, infection, and ototoxic drugs or agents.
Step-by-step explanation:
The cause of postnatal hearing loss can be attributed to various factors, including:
- Genetic factors
- Noise exposure
- Infection
- Ototoxic drugs or agents
Genetic factors can lead to the development of certain hearing disorders, such as congenital deafness. Noise exposure, especially to loud sounds, can damage the delicate hair cells in the cochlea and result in hearing loss. Infections, such as measles or mumps, can also cause hearing loss. Additionally, certain medications or exposure to ototoxic drugs or agents can have a negative impact on hearing.
