The condition can be fatal if left untreated, but the tetanus vaccine and improvements in treatment mean deaths from tetanus are now very rare in the UK. In 2013, there were only seven recorded cases of tetanus in England and Wales, and no deaths.
Sound pressure is measured in decibels (dB). Like a temperature scale, the decibel scale goes below zero. The average person can hear sounds down to about 0 dB, the level of rustling leaves. Some people with very good hearing can hear sounds down to -15 dB. If a sound reaches 85 dB or stronger, it can cause permanent damage to your hearing. The amount of time you listen to a sound affects how much damage it will cause.
The project, Keep The Sound, highlights the damage caused by listening to high volumes for too long. It found the majority of young people are listening to music in excess of 91 decibels â higher than the maximum recommended level of 85 decibels. One in four played music at levels over 100 decibels. At this level of exposure, even 15 minutes a day could cause permanent damage. The effects of this damage may not be noticed until years later, when it is too late to correct the situation. Daily users of portable music players are particularly at risk.
