Although you can't reverse SNHL, you can take steps to keep it from getting worse. For example, reduce your exposure to loud and sustained noises and wear earplugs if exposure is unavoidable.  Reconsider going to rock concerts or sporting events such as car racing. Turn down the volume on you MP3 device while listening to your favorite music. Never stick a sharp object into your ear! Sticking a pin, pencil, knife or other sharp object into your ear may perforate your eardrum and lead to permanent hearing loss.  A perforated eardrum may be accompanied by pain, dizziness, and a ringing in your ears. Although some medications are clearly life saving and needed on a regular basis, others that deal with minor symptoms such as headaches may be negatively impacting your hearing.  Salicylates such as aspirin have been shown to disrupt electrical current in the inner ear.  Medicines used to treat high blood pressure and cancer also create a higher risk of hearing loss. Some chemotherapy drugs can even cause permanent hearing loss. These drugs include cisplatin, 5-fluorouracil, bleomycin, and nitrogen mustard. High doses of aspirin can cause temporary hearing loss.  Antimalarial medications such as quinine and chloroquine can also cause temporary sensorineural hearing loss. Don't let your cold, flu, sinus infection or allergies get out of control (or become chronic / recurring) such that it impacts your ears and reduces your hearing. Keep your immune system strong so that it can naturally fight off infections.  Getting lots of sleep, drinking lots of water, controlling your stress and eating nutritious food all positively impact your immune system. Some serious health conditions, such as diabetes, may lead to hearing loss as well. If you have diabetes, do what you can to keep it under control and seek immediate medical attention if you start having ear pain. This may be a sign of a condition called necrotizing external otitis, which can lead to hearing loss and even death.

TL;DR in Chinese:
采取预防措施，以免大声的噪音进一步损害听力。 保护耳朵，以免被利器所伤。 药物可能会影响听力。 及时治疗其它健康问题，以免它们影响听力。
