Step 2: Pick a sound to use, like a beep or tone, and make sure it plays at the same volume and pitch every time. Test it before starting to make sure it works properly. 

Step 3: Gather people of different ages to test, like kids, teens, adults, and older people. Make sure you explain the experiment to them and get their permission to participate. 

Step 4: Have each person sit in the chair at the marked spot. Tell them to raise their hand or say "yes" if they hear the sound. Let them know the sound will only play once. 

Step 5: Play the sound at the set volume and wait to see if the person hears it. Write down if they heard it or not on a chart. Also, write down their age. 

Step 6: Do the same thing for all the people you’re testing. Make sure you keep the volume, distance, and sound the same for everyone. 

Step 7: After testing everyone, look at your chart to see if people of different ages heard the sound or not. 

Step 8: Use what you found to figure out if age makes a difference in whether someone can hear the sound. 

2nd person 20-30 

3rd person 30-40 

4rd person 40+ 

Step 1: Find a quiet room where there won’t be any background noise. Set up a speaker or headphones on a table. Use a measuring tape to mark a spot 2 meters away from the speaker where each person will sit. 

Step 2: Pick a sound to use, like a beep or tone, and make sure it plays at the same volume and pitch every time. Test it before starting to make sure it works properly. 

Step 3: Gather people of different ages to test, like kids, teens, adults, and older people. Make sure you explain the experiment to them and get their permission to participate. 

Step 4: Have each person sit in the chair at the marked spot. Tell them to raise their hand or say "yes" if they hear the sound. Let them know the sound will only play once. 

Step 5: Play the sound at the set volume and wait to see if the person hears it. Write down if they heard it or not on a chart. Also, write down their age. 

Step 6: Do the same thing for all the people you’re testing. Make sure you keep the volume, distance, and sound the same for everyone. 

Step 7: After testing everyone, look at your chart to see if people of different ages heard the sound or not. 

Step 8: Use what you found to figure out if age makes a difference in whether someone can hear the sound. 

2: place speaker at a marked position in a room with the participant sitting in another marked position  

3: record volume that the speaker is playing at and the time of the recording when you start it and record the name/number and age of the participant 

4: instruct the participant to stand up when they can no longer hear the pitch coming from the speaker 

5: play the sound and time how long it takes for the participant to stand up 

6: record the sound in a document and reset the recording to where you originally started it  

7: repeat for other participants 

2. Start playing the Hz and times it by 2 every time  

3. Note down when the person starts to hear the sound and note down when they cannot hear the sound anymore  

4. Repeat this for every person, repeat the with two times for every person.   

2. Unwillingly play the 13000Hz sound wave on 110 decibels on the tone generator for 10 seconds. 

3. Ask if the test subject could hear the sound or not, and record the data on a chart 

4. Repeat steps 2 and 3 three more times for the test subject for better results. 

5. Repeat steps 1-4 for the following aged men: 35, 50, 65, 80 

6. Record all data and evaluate hypothesis  

2. Unwillingly play the 13000 hz sound wave on 110 dB on the tone generator for 10 seconds. 

3.Ask the test subject if they can hear the sound and record the data. 

4.Repeat steps 2 and 3 with people of vastly different ages. 

2.Contine in intervals of 2X until the person says its getting harder

3. Then increase by 2 hertz

4. Track data

5. Repete for each person
