VIDEO: What is Echolocation?

I recently put this video together to spread the word of echolocation to those who need more information.  It provides a clear cut, simple explanation of exactly what it is and how it's used.

If you are still unsure of what echolocation is, I'm sure this video will clear things up.  If you're still skeptical of echolocation, that's alright!  That just means you have the ability to think critically which will inevitably help you learn.

As always if you have any questions or comments feel free to leave them below or contact me directly.

Does the same noise sound the same to two different people?

Well that is indeed quite a question. After all, different people tend to react differently to a given stimulus. One person may find a specific stimulus annoying or even outright disturbing can be both soothing and relaxing to another as it depends largely on the culture and upbringing of said persons. For instance, in many cultures, black has been widely associated with ideas like death and evil while in Japan and other North Asian cultures, they use white to symbolize death instead. That is why one kind of sound may symbolize two radically different ideas for two people depending on their culture. A bell tolling may mean a wedding for one person, but might actually be an alarm to another.

Also, take note that a person’s ear structure also figures largely with how one actually hears and perceives sound. While there are animals in the animal kingdom that only possess exposed eardrums to receive and process noise, humans have the distinct ear shape with the rest of the more important faculties placed within the head proper. This is so that noise hits the structures and is channeled into the eardrum instead of just letting random noise from all directions that can be found in more primitive animals. Also of note is the fact that the position of ears can also differ from person to person, leading one to perceive noise differently from others. The sensitivity of ears is also another significant factor and some are more likely to perceive subtle vibrations than others.

What are Sound Reflectors?

Have you ever attended an orchestra or an indoor concert? Did you notice anything particularly in your general surroundings? Well, if you didn’t, then perhaps you’ll take note of the way the sound seems to be more solid and seems to reverberate in your bones while in the concert hall as opposed to what you’ll hear in an open-space concert. If you’re wondering what makes it all possible, then the explanation is rather simple. They make use of what are called Sound Reflectors which are relatively simple structures that are placed into the walls to make the musical piece reflect back towards the audience, giving it a fuller and louder effect.

So what are sound reflectors, really? Well, they are simply panels of wood that have been carved into a convex shape that will allow them to reflect sound directly into the audience in order to hear whatever is on stage with even greater clarity. Composed mainly of plywood with some gel to make them even more reflective of sound, this is what makes indoor concerts, lectures and seminars successful thanks to the way that sound is carried and distributed. This is what makes sound reflectors also a must in so many establishments like lecture halls, auditoriums and places of worship.

So next time you attend a huge public gathering such as a seminar or concert and are just wondering how they make sound travel and reverberate throughout the space without making use of any additional speakers, take note and look up as they are probably making use of sound reflectors.
