Learning about Hearing

                                                                               



                                                 Room Fourteen Learning about hearing.

                                                 
                 A big group of  Lynfield collage teenagers came to our school to teach different classes                                  about hearing and what you can do to to help yourself from getting bad hearing loss.
                              Now I am going to tell you a bit of a recap of what I learnt.

 First of all you know how we have the unite of measure for meters well sound also has a unite of measure
              now when these girls asked that question a phew people said " is it Volume" well your wrong the              unite of   measure for sound is called Decibels the limit for decibels is  the number 85 higher than that                                           number that  means it is too loud. Any lower is safe.

                                 

Another thing that I learnt was that everything is made up of molecules so when we did an  experiment with some string a ping pong ball  and a scientific tool we used it to make the vibrations so when we banged the tool on the table when it was vibrating then stayed still while the ping pong ball was discharging from the tool.

                                       There were three main things that we all learnt that was
                                         if your music in your car is too loud Turn it down
                                        If someone has a loud siren or is playing music near you an you think
                                        it is too loud. Walk away Now the last one is using PROTECTION. Now with                                             me personally I think that is the most important. Because having hearing loss
                                        is not cool so if you have parents or if you have a dad that works around big                                               machines and its really loud you can not only buy ear plugs for yourself to keep                                              you safe but also for  your parents or anyone else who needs them.

                                         This is us playing a game about what it sounds like when
                       you have good hearing and what it sounds like when you do have hearing loss.

Here is us when we got picked to stand up and hold these cards that pitchers of things that may be safe or unsafe for your hearing. Did you know that the most dangerous thing that would be to loud for your ears would be and rocket launching.That would be 165 decibels but the limit is 85 so even if you listen to it for at least 5 seconds you could get really bad ear damage.

                            This is Hannah and Zainab holding a sound o meter to see if walking a
                           step a way form loud sound will make a difference to your hearing.
