Crescendo Gardening earplugs are designed to block much of the noise produced by the power equipment used for lawn and garden maintenance.

Lawn mowers can produce 95 to 105 decibels and chain saws, 100 to 125, according to Dynamic Ear Co., the Dutch company that makes Crescendo earplugs. That’s louder than the limit of 85 decibels considered safe in a working environment.

The gardening earplugs reduce noise by 24 decibels. The design also has an open-air passage that keeps the ear ventilated for comfort and minimizes the feeling of obstruction.

Both the ear tips and filters are washable.

Crescendo Gardening earplugs are available for $19.95 at Ear Plug Superstore (www.earplugstore.com), with discounts for larger orders. Shipping is extra.
