Hearing-impaired people need time to slowly adapt from a silent world back to a lively environment. Suggest starting use at home, trying 1 to 2 hours daily to adapt to family speech and home ambient noise. After getting used to it, gradually increase wearing time until comfortable wearing 5 to 6 hours at home daily, then try in quieter outdoor environments. You must have sufficient mental preparation before going to noisy places like tea houses or markets. For first attempts, suggest slightly lowering the volume; if wearing binaurally, try removing one first and adapt step by step.
