What tasks could you carry out to test the above situations? After doing some analysing and some research I have focused on some tasks that I can carry out to test the effect of hearing in a noisy environment and the effect of learning in a noisy environment.

First investigation: (testing out the effect of hearing in a noisy environment)

Producing or playing loud noises while reading out words and seeing how well the other person across the room can pickup the words.

Trying to call someone in a noisy environment without them being aware that you are calling them.

Second investigation: (testing out the effect of learning in a noisy environment)

Playing or producing loud noises while a person tries to read.

Playing or producing loud noises while another person is trying to memorise something.

What sources of loud noise are you going to have?

The loud noises which I plan to have include:

Loud music

Clapping

People screaming over eachother.

Will you have a control?

The controlled variable will be the same noisy environment and the same loud noises at the same DB (Decibels).

Will you need to repeat the experiment?

The experiment will be repeated with 3 different people using the same loud noises at the same DB and the same noisy environment, the three people will be my three younger sisters.

How will you measure your findings? What scale are you going to use?

First investigation: (testing out the effect of hearing in a noisy environment)

Producing or playing loud noises while reading out words and seeing how many words the person in the same room can hear. (The person which is being tested has to write down all the words that are heard, no words are to be repeated and a word is to be pronounced every second for one minute.)

Timing how long it takes a person to realise that you're calling them in a noisy environment.

Second investigation: (testing out the effect of learning in a noisy environment)

1. Measuring how many words a person can read out loud in a row before they make a mistake due to other words being played in the background. (There will be 50 words to be read out, there is no stopping to be made during the readings)

2. Measuring how much words a person can memorise out of 10 words said after eachother while music is played in the background/ or a person claps. (Words will not be repeated)

How many people will you use to carry out the experiment? Any particular age group?

There are three people that are going to be tested, my three sisters, Elissa aged 15, Savannah aged 13 and Samar aged 8. There is no particular age group because Different ages might show a difference on the effect on noisy environments on hearing and learning.

How will you record your data?

My data will be recorded in tables; every thing im testing will be in a separate column. Each person will be tested 3 times to give me more accurate results.

Part B: Results

First Investigation: Part one (trying to see how many words can be heard and written down in 1 minute (a word is read out every second, so the maximum amount of words that can be written down is 60)

Pictures (Video did not upload there was problems so photos are still a visual so here they are)

(The photo above is a photo of my sister Elissa writing down words as I read out words to her)

( Above is the photo of the volume, the speakers were put up to Volume which the handbook says is equivalent to 90db ) ( Any louder and it can cause damage to the ears)

( Above is a photo of my sister reading a book out loud trying not to make mistakes, the music was at 90db) ( as she reads I record the amount of words she can say without making mistakes ) ( and the I etc are not counted as words )

Part C: Discussion

My results show that playing loud music (at 90db which is what I considered loud and what I tested my people on) has an effect on the hearing and the learning of people. My results clearly show that the people I was testing were affected by the loud noise. Their concentration levels lowered, their brain was not able to handle music in the background, they were unable to memorise words and they made mistakes while reading out and they have to be called multiple times so you can get their attention. I recommend that if a person was to study or was to listen to something, they should sit in a quiet room away from loud noises, or block their ears with ear plugs or something along those lines. The reason for this is that it affects your concentration and it is a very big distraction, And I also recommend that if you are trying to call someone in a noisy environment, don't get frustrated because they don't answer, there minds are distracted and you may have to call out their name multiple times for them to respond. So I recommend that for your studying, or if you like reading, stay away from noisy environments.

http://www.answers.com/topic/hearing-impairment-1 Visited on 21/ 08/2010 states that hearing impairment can be of various degrees, including mild, moderate, severe, profound, or total. The degree of impairment typically is categorized by the loss of hearing sensitivity, that is, how loud sounds must be for a listener to hear them. The degree of impairment can refer either to the loss of hearing sensitivity for individual pitches of sounds for each ear separately, or to an overall loss of hearing sensitivity for both ears. Research shows that hearing starts to be lost when sound is being projected at 85db or over.

http://www.buzzle.com/articles/causes-of-permanent-hearing-loss.html Visited on 23/08/2010 states that Permanent hearing loss can be caused due to many reasons. It can be gradual, for e.g., age-related hearing loss (presbyacusis) or sudden hearing loss, for e.g., viral infection. It is a fact that sensor neural disorder results in permanent hearing loss, whereas a conductive hearing loss may be temporary or permanent. Let's take a look at the causes of permanent hearing loss. Exposure to extremely loud noise (more than 90 decibels),

http://www.kemt.fei.tuke.sk/Predmety/KEMT320_EA/_web/Online_Course_on_Acoustics/intelligibility.html Visited on 24/08/2010 states that In a disturbance-free environment, normal speech levels fall between 55 and 65 dB In specific situations, levels may reach as high as 96 dB when shouting a warning, or as low as 30 dB when whispering softly. It should be noted that speech levels vary significantly between individuals.

Part D - Conclusion

My aim in this experiment was to identify data sources and choose equipment or resources to investigate the problems associated with hearing and learning in a noisy environment. My experiments' results and further research shows that a noisy environment has a very big impact on the hearing and learning of people. The concentration level in a person's brain is lowered and a person gets easily distracted by the sound. As I type this up I get distracted by the TV sounds from other rooms and people screaming and shouting. Three people were tested, Three times each and 2 different experiments for hearing and learning and all 4 experiments show that loud noises have a big affect on concentration and trying to memorise. A Justified answer which I could provide to conclude my experiment is that excessive noise in an environment is very bad and that it affects reaction times, hearing, learning and decreases concentration.
