I think the best thing would be to try to keep excessively loud or repetitive noises to a minimum ... She is not used to life being so loud and it's everything that's loud not just voices, she's hearing some sounds for the first time ....I'm sure it's pretty scary for a two year old ... it takes a long time for her to learn to tune out certain noises. Maybe the hearing specialist can turn down the hearing aids for awhile and then gradually turn them up.
