Online Tone Generator - Hearing Test Results: Is your hearing better or worse than average? Results from the Online Hearing Test. Is your hearing better or worse than average? A random sample of 350 results posted in the hearing test comments has been used to compile an age vs frequency graph. It shows the highest frequency at which people of a certain age can hear up to. Hover over points on the graph to see the specific data used. Graph 1: Raw Data Graph 2: Data Averaged by Age Graph 1 shows the entire data set in its raw form. Graph 2 shows the data when all the measurements for a particular age are averaged. Please note: This is a not scientifically rigorous test and has been created to simply highlight the variations in human hearing in a fun and accessible way.

Tonos de celular indetectables (experimento en base a la edad) Este experimento se basa en la diferencia que existe entre la audición de las personas adultas y los jóvenes. Es natural que con el paso de los años la capacidad de audición disminuya especialmente hacia sonidos denotados como agudos (de alta frecuencia). Es por ello que muchos adultos de edad avanzada necesitan subir el volumen de la televisión a niveles que pueden ensordecer a un niño. Este fenómeno en el cual la capacidad de audición disminuye especialmente hacia altas frecuencias y volúmenes bajos se conoce como presbiacusia o bien ensordecimiento propio de la edad. Cabe destacar que no tiene nada que ver la presbiacusia, la cual se considera relativamente normal dentro de algunos parámetros, con enfermedades que degeneran las capacidades auditivas de manera distinta a la propia degeneración por la edad. Materiales: Procedimiento Podemos proceder de dos formas: la primera sería como en una prueba de audición convencional. Por último, vamos a hacerlo más interesante todavía.

Try It: Can You Hear These Sounds Only Young People Hear? How young are your ears? (Photo: Getty Images) Did you know that, as we age, we can no longer hear certain high-pitched noises as well as we did during our youth? This ear-aging process is called presbycusis, and it can begin as early as 18. So, let’s get to it: How young are your ears? 8000 hertz (cycles per second): Everyone should be able to hear this frequency. 12,000 Hz is hard for anyone over 50 to hear. 15,000 Hz is difficult for anyone over 40 to hear. 17,400 Hz is the frequency only teenagers can hear! Some major retailers actually use this science to keep teens from loitering outside their stores. If you ever want to play a trick on your teen — or if you’re a teen, a trick on your friends — download this app from iTunes, called Frequencies — Sounds only teens can hear! On the flip side, teens are striking back by employing these pitches as ringtones, so they can get calls that their parents and teachers can’t hear.
