Trying to be considerate, I tried to browse old posts on my usenet server related to this topic, and I noticed that the product
Peltor H10A Professional Noise Canceling Earmuff
was used by some. It seems "healthy" to me not to have everything completely muted, and being able to hear voices at normal voices would be a plus (though I'm not sure how well this product would help satisfy either of those goals).
Is the one above a "good, safe choice"? Any other models you might recommend I consider? I suppose if I had a pair, I might start wearing them when I mow the lawn, though that idea hadn't occurred to me before.
Thank you, Bill
