It is generally okay to wear just one hearing aid, especially if you have hearing loss in only one ear.
However, wearing only one hearing aid can have some drawbacks. For example, you may have difficulty localizing sounds, making it harder to understand speech in noisy environments. You might also experience a difference in volume between your ears, which can be uncomfortable or disorienting.
If you have hearing loss in both ears, it is usually recommended to wear two hearing aids. This helps to improve your overall hearing ability, including speech understanding, sound localization, and sound quality.
Ultimately, the decision of whether to wear one or two hearing aids is a personal one. You should discuss your individual needs and preferences with your audiologist to determine the best course of action for you.
