The frequency of testing for hearing loss depends on various factors, including your age, overall health, and exposure to loud noises. As a general guideline, adults should have their hearing tested at least once every decade until the age of 50, and then every three years thereafter. However, if you experience any signs of hearing loss, such as difficulty understanding conversations or ringing in your ears, it is advisable to seek a professional evaluation from an audiologist. They can provide personalized recommendations for how often you should have your hearing tested based on your specific circumstances.
