DS is 7 next month and talks at a loud volume, all the time. As in, when ever he talks the volume is always higher than any other child. (He also talks non-stop but that's a different issue.) He's had his hearing tested when he was a newborn, when he was 2.5 and about a year ago by audiology students who came to his school. (He has had a severe speech delay hence the hearing tests.)
Has anyone experienced anything like this? It's driving us insane! My day is constantly punctuated by telling him to talk more quietly. After the 15th time I tend to get a bit short tempered.
