15. Hearing range.

Bulgaria Investigate how the hearing range of humans is affected by their age and other external factors.

Croatia Devise a way to examine the hearing range of different species of fish.

Georgia Investigate how mammal species with different lifestyles react to different frequencies.

Greece-Alliance There is a considerable variation in the range of frequencies that can be heard by humans. We will investigate the lowest and highest audible frequencies, that human can hear, depending on their age, gender and the influence of otitis. Moreover, we will investigate how hearing of loud music can cause a drop of hearing ability.

Greece-Fryganiotis How does age affect the range of audible frequencies in humans?

Iran-Innovative Researchers Effective parameters on auditory differences. Frequent use of headphones. Example of an animal that can hear beyond the face. What is the importance of frequency in this issue and why should we know it? What causes some animals to hear ultrasonic sounds? Explain the structure of the ear. What is Sound?

Iran-Valeh Explain the structure of the ear. What is Sound? Two important properties of sound. Suggest a problem to investigate the lowest and highest audible frequencies for specific species of societal groups. Experiments that can be done for finding hearing of animals and humans. Checking the range of hearing between different animals.

The human ear is the auditory and balance organ that detects and analyzes sound by transmitting or converting sound waves into electrochemical impulses and creates a sense of balance in us. Two important properties of sound are frequency and intensity.

Kazakhstan-Bobek The audibility by the human ear varies between all individuals. The audible frequency range on average is between 16 Hz to 20 KHz, and the intensity detected by the average person is between -10dB to 130 dB.

Kazakhstan-RFMS Study the parameters affecting the hearing range of different creatures.

New Zealand Humans and dogs have different ranges of audible frequency. Investigate and compare the highest and lowest audible frequencies for the two societal groups.

Romania-LIMITLESS Analysis of the audiograms depending on the hearing problem of the subject.

Romania-NITRO Humans hear weaker frequencies better than the higher ones. Perform an experiment to outline the limits of the human hearing. Compare the results to the ones from the other investigated species.

Russia-Unartificial Intelligence Let's try to measure how the audibility of high and low frequencies changes in people of different ages.
