AC/DC have postponed their US, tour after singer Brian Johnson was warned by doctors that he was at risk of“ total hearing loss". This is unsurprising that the Australian band has been pumping out the hard rock decibel(分贝). But deafness isn't only a concern for rock musicians. Anyone around music a lot has reason to be equally worried.
When you are exposed to music, risk to hearing arises from a combination of how loud the sound is and how long you' re exposed to it for. If you visit a nightclub with music at 100 dB, then after only 10~15 minutes the exposure is potentially damaging. In a quieter part of the club, but where the music is still loud enough that you have to shout at your friends, them you could be there for a couple of hours before having to worry about your hearing. Of course music frequently exceeds (超过) 80~85 dB, but what counts most in assessing the risk to hearing is the average exposure.
Exposure to high noise levels often causes temporary deafness-something many people have experienced after going to a nightclub. While hearing usually recovers , repeated loud exposure leads to permanent hearing damage. Initially, this damage is unlikely to be noticed by the listener. Problems only become significant in middle age when the noise-caused hearing loss combines with the natural loss of hearing due to ageing.
Often orchestras employ screens or “musicians ear plugs” to block sound from the loudest instruments. These decrease sound without completely blocking everything out and are very useful in rehearsal（训练),but get in the way of balancing the sound in a concert. Professional orchestras also look at how they schedule music to ensure that musicians are exposed to a mixture of quiet and loud pieces. Given how loud their instruments are, drummers are particularly at risk, but using era plugs can go some way to reducing potential hearing loss. For rock and pop musicians, using in-ear monitors has the potential to reduce noise exposure.
Improved technology means the number of musicians having to give up performing could decrease, But student musicians need to be educated about the dangers of noise-caused hearing loss. The increasing use of headphones will also work against this. Unless people are careful with the volume level on their portable music players, hearing loss caused by music will increase.

How many times have you seen a "lost dog" poster hanging up on a street corner? John Polimeno was at a coffee shop when he spotted one of those posters. He thought about his own experience looking for a lost pet, with crying children in the backseat, and knew there must be a better way. After seeing several of the coffee shop customers glued to their smartphones, Polimeno had an idea.
It's a smartphone app called Finding Rover, and it uses facial recognition technology to reunite lost dogs with their owners. Polimeno is the founder and CEO of Finding Rover. Launched in the Apple Store in late 2013, followed by Android and Web versions, the app uses software developed by Polimeno and a team at the University of Utah. They studied facial recognition technologies for pets, locating all of their unique facial features.
It works like this: Pet owners upload a picture of their dog. Shelters and other Finding Rover users upload pictures of found dogs. Once a dog is reported found, its picture is scanned through all of the "lost" pictures. A found dog and lost dog are then matched based on the technology, and the worried owner is notified.
Laura Steveson of Chula Vista, Calif., was one of those owners. She describes her 5-year-old Brussels Griffon, Monchichi, as "her everything." They have been through a lot together: divorce, remarriage, moving, and everything in between. When Steveson and her husband traveled to City of Hope Cancer Center for his illness, Monchichi went missing. Steveson says she "fell to pieces" and her husband, near the end of his week-long treatment, started searching for ways to find their pet. He happened upon Finding Rover, and Steveson uploaded a picture of Monchichi. Minutes later, Steveson received an email that her dog was safe and found at the San Diego County Department of Animal Services. She was glad to receive piece of mind so quickly in such a stressful situation.
Currently, Finding Rover only helps find lost dogs, but next month cats will be added to the app.

I have many things in common with my dad, like music taste and sense of humor, but sadly reading isn’t one of them. I can happily spend a whole day with a book, but my dad can’t read a book for longer than about 5 minutes. He reads emails, websites and documents for work, but not books. I think that siting down to read for just 15minutes a day is a good way to relax,So I introduce him to reading.Giving yourself a goal or challenge is a good way to change a habit or achieve something,so why not try to create a new habit of reading?
My dad is by no means the only person who avoids books. I know lots of people would rather relax on their computers or in front of the TV. Everyone is different and has their own interests, but I think there are lots of benefits to reading, which screen-based activities don’t offer.
Firstly, it’s better for your eyes. Looking at screens can be very stressful for you eye muscles, and clearly you should avoid looking at screens for an hour before bed, to get a good night’s sleep.
One thing I personally love about reading, is being transported to another world—I often forget the time or things that are going on around me! Reading is a great way to switch off before you go to bed, because you think more about the world of the book, rather than the real world and the problems you have during the day, and you can truly relax. While watching a film,I often talk to my flatmates,send texts,or cut my nails,A book,on the other hand,commands your full attention.
