If you are a fan of DJs such as Vicetone, Nicky Romero and David Guetta, I am sure you must have heard them saying the phrase in the topic of this post so many times in live shows but notice the word in uppercase.
Hearing properly is the most important thing when it comes to producing music, listening to the radio or even when having day to day conversations. Like all other important things in life, hearing also must be protected. Prolonged exposure to loud noise could lead to Sensorineural hearing loss, which is caused by damage to the inner ear and/or auditory nerve .

Now, do not panic ! Here are some tips suggested by NHS to protect your hearing  :
- Do not listen to your personal music player at very high volumes and never to get rid of background noise.
- Listen to your music at 60% of the maximum volume of the audio player for no more than 60 minutes a day (also known as 60:60 rule). Most MP3 players and mobile phones have the “smart volume” feature, which helps to regulate the volume output.
- Try to use noise-cancelling or muff-type headphones when listening to your personal music player. These will block the background noise, so that you can listen to your music at a low volume level, but take regular breaks even when using these (There is a post on my blog on how noise-cancelling headphones work, if you are interested). In-ear headphones are less effective at filtering out background noise.
- Use ear plugs when you are listening to live music (No, I’m not crazy). You can still enjoy music while wearing these and are widely available at many live music venues.
- If you are in a vehicle, do not listen to loud music for too long because listening to music in a confined space increases the risk of hearing damage.
