![]() ![]() Your ear has a very difficult task now, because it has to actuallyīreak this frequency, F3, down into the two simplerįrequencies, F1 and F2. Weird jumbled frequency, which we'll label F3. Two frequencies together, you'd get this really Two frequencies together, would be something kinda weird. What that would look like, if we were to add these To both somebody talking and clapping their hands at the same time. If you look at these twoĭifferent sound waves, they both have different frequencies, but you might have noticed - let's imagine that this frequency, F1, is generated by hands clapping and F2 is generated by somebody talking. Waves actually travel further, and they actually penetrateĭeeper into the cochlea, which is a structure that we'll This actually happens in the ear, so these lower frequency sound Sound waves of lower frequencyĪctually travel further. Sound wave right here is F1, and that this one over here is F2. Of the sound wave, it's perceived to be a different noise. If I clap my hands even faster together, or if there's something else that's a higher frequency,Ī higher-pitched sound, the sound waves would beĬloser to one another, and it would look something like this. Basically, there are justĪreas of high and low pressure. Over here would be anĪrea of low pressure. Basically, what I'm drawing here is, up here would be an area of high pressure. If we draw this graphically, it might look something like this. Really, really close together, or really far away from each other. These areas of high and low pressure are known as sound waves. ![]() As it's escaping, it creates these areas of high and low pressure. This area of pressureĪctually tries to escape. As you bring your hands together, you're actually addingĪll the molecules up, and it creates this pressure. Basically, what is effectively going on is the air molecules hereĪre getting pressurized. Hands are even closer together, that the air molecules They're really compressed, so they're really, really close together, and they're super-compressed. What happened was all these air molecules that are just floating around, Towards each other - so here we are just drawing the A little bit later in time, as the hands are moving Then all of a sudden, the hands are moving towards each other, and all of a sudden, this space that these air molecules They're just floatingĪround doing their thing. Hands are a whole bunch of these air molecules. I'm drawing right now, let's imagine that they're In between your hands are a whole bunch of little air molecules, They're moving towardsĮach other fairly quickly. When you clap your hands, the lines move towards each other, so your hands are moving Hands, it makes a sound, and it makes a very distinct sound. Whenever you clap your hands, you have learned fromĮxperience that people, when they clap their What exactly is a pressurized sound wave? Let's look at an example. We'll discuss this in furtherĭetail later in the video. Known as a hair cell, and the hair cell isĪ specialized receptor that's found within the cochlea. In the case of audition, that receptor is something The second thing, aside from the stimulus, is some sort of receptor that's sensitive to the stimulus. That needs to be present in order for us to hear anything. Known as a sound wave - so, a pressurized sound wave. In the case of sound, that stimulus is something In order for us to hear anything, two things have to happen. Our sense of sound isĪlso known as audition. Voiceover: In this video, we're gonna talk about our sense of sound. ![]()
