In adults, most hearing loss happens gradually. While hearing loss is more common as we age, people of any age can have a hearing loss that interferes with their ability to communicate. Most people first notice difficulty understanding others, especially in noisy environments. Others may notice they have trouble following conversation when two or more people are talking at the same time. Other common signs are asking others to repeat themselves, or feeling like people seem to mumble. If you have concerns about your hearing, seek the services of an audiologist for an evaluation.
