Hi, Sound levels at parties are usually higher than safety level of what a normal average person s hearing sensitivity. Problems following exposure to loud sound may be immediate or delayed, may be temporary or permanent, partial or total, reversible or irreversible. Exposure to a loud sound even a single and transient is enough to cause damage to ear. You need to have audiometric test at least once so that it s progress can be decided and prognosis can be predicted in follow-up audiometric investigation and a treatment protocol can be planned accordingly. Ringing in ears may get off but can t predict. All depends on how serious your inner ear or a sensory nerve affected. Hope I have answered your question. Let me know if I can assist you further.
