School music teachers 

are being warned to wear 

earmuffs or stand behind 

noise screens.

This is because beginners tend to 

blast away much louder than 

professionals, reports the Daily Mail.

The most potentially deafening instrument

is the cornet, 

with just one honk being enough to

cause permanent ear damage.

And standing in the direct fire of

instruments such as the flute, oboe

and saxophone can become risky

after just 15 minutes, the Health and

Safety Executive warns.

“Sound levels produced by groups of

student instrumentalists are likely to be

higher than those produced by a

professional group of players because

of less-developed technical abilities and

natural exuberance,” the HSE said.

The warning has been posted on the HSE website.

 It sets the lower safe daily limit for exposure

to a prolonged noise at 80 decibels.

.

When officials visited a school, 

they found that noise in a cornet lesson hit

140 decibels. 

In comparison, a pneumatic drill makes

a 100-decibel sound and 140 decibels

equates to a plane taking off.

A school that allows staff to be exposed

to the cornet without protection would

likely be in breach of noise regulations,

the HSE warns.

“It is therefore crucial that a thorough

noise control strategy is in place before

any exposure to loud noise might occur,”

it said.
