Once I was searching about the infamous《施氏食狮史》 on the Internet I came across the poem that you introduced here. After that, I found a KZfaq video about it, but the most absurd thing is that the first part of the Chinese Test in the video was the DICTATION exam of 《季姬击鸡记》, and the minimum point to continue the test was thirty. Can some native Standard Chinese speakers or someone major in Chinese language like me pass the dictation? I wonder... Link of the video in question: kzfaq.info/get/bejne/rs59eLWlktKniqs.htmlsi=Cfw7WQcq87HfSiAo

Interesting, but if it is like you say, a simple echo and because of the number of stairs, why can't it be heard the sound in the four sides? and you can say, maybe because the thing it has on the top... which is strange because it is heard the same sound on two sides ....

Thanks! Thanks to your video i was able to hook up a 16Bar pressure sensor to my arduino. For some reason my pressure was running from 4mA to 12mA full scale. Also first time i measured 2mA with 0 pressure, after having applied pressure 1 time , funny enough it showed 3.95mA when no pressure was applied. So then it was working as expected. But the max stayed 12mA. The same sensor PT506 exists also in a 25Bar version, maybe they mislabeled mine? However after changing the formule it worked like a charm and the Arduino showed what i was reading on the pressure regulator. Thanks your video was awesome and clear and helped me how to connect 2 wire sensors. So i learned something new. Much appreciated!

So does this mean there were some Fourier transform involved? If some steps were raised or lower, made thinner or wider, would it produce a different sound? You could technically make any sound wave using Fourier transform like with music synthesizers. Is that what is happening here but with a clap sound? Could it be done with other sound instead of a clap? Could some sound be easier to transform than other into certain sound or some limitation to what the sound could be? If instead of 91 clap echoes but 1000 echoes and if you slow it down and change the pitch or frequency of those individual clap sounds, you can make it sound like some other sound wave. That is what I'm guessing you can do. The simulated sound in the video sound like a low quality version of a sound wave (bird chirp).
@werewolfwu2 ай бұрын
What physically happens here is a convolution of clap sound and the impulse response of the pyramid reflection. Then you can apply that knowledge however you'd like.

Hi! Very interesting video on a really surprising effect! I have a few questions related to this: 1) You are saying that wave diffraction is happening here : to what extent would this affect the phenomenon? 2) The 2D geometrical analysis you made was really convincing! I am surprised that the length of the steps doesn't influence the phenomenon : would a 3D-consideration change anything on the results? I mean, if you used a really small length of the steps, but the same height and depth as the pyramid, would it give the same results in situ ? 3) After watching your video, I noticed it was possible to produce the same effect on a large construction site fence (with small "steps" of 3 cm), but not on a small staircase of roughly 90 steps (1 cm for height and depth). Since both structures are really thin, would acoustic impedance have a role in this effect ? Thanks by advance if you can help me understand this !
@werewolfwu8 ай бұрын
Glad you found it useful! To answer your questions: 1) diffraction serves to disperse the reflected sound wave so that you can hear the echos from where you are standing. Without diffraction, the sound will reflect off the higher stairs and simply go up and away from you and you won't hear it. 2) Length of steps very much matters. For sake of simplicity I'm only talking about the case where step height = step length/depth. 3-D model WILL CHANGE things to a certain extent, mostly in the "color" of the sound, but the basic idea is the same. 3) This effect is akin to diffraction grating in optics, so with different step size you get different frequencies. at step size of 3cm, the frequency you hear is about 5.7kHz, that is VERY HIGH frequency! At 1cm step size, the frequency is now 17kHz! Most people cannot hear this frequency clearly. I know I totally cannot, proven with experiment. Hopefully this helps!

@@werewolfwu Thanks a lot for your really clear answers! I'm sorry for wasting you time, other questions are coming to my mind : 1) For example, would it be possible to emit other sounds, like a monofrequency signal ? Because based on the geometrical model, the gliding pitch effect would still occur... but I have a feeling such a thing wouldn't happen in situ (if so, why ?) 2) Does the duration of the signal have an importance ? Or do you think interferences would happen if it is too long ? 3) And are you planning to do a video to explain diffraction effects on this pyramid? The explanation you gave was really nice and I would be pleased to learn more about it applied to this context!
@werewolfwu8 ай бұрын
Glad you like the answers! 1) yes, it is totally possible, as long as you have the right geometrical shape. 2) the duration of the incident signal is important (short, ideally a pulse, hence clapping sound is ideal) for ease of analysis if you are trying to use echos to emulate something (like a bird). The duration of the echo signal is important for human perception, meaning if it is too short it cannot be perceived. 3) that seems to be a topic that is too esoteric to be made into a video at least for now. There are a lot of other interesting things to talk about in this world.

(A vertical pvc pipe set-up with 10 reed switches outside "encapsulated in silicone" inside the 1' pvc pipe a Styrofoam float with a neodymium magnet on top) Besides the disadvantages of a myriad of wires (I used cat6 cables) the water would eventually seep through the silicone and cause "erroneous readings" This will help me set-up a single wire pair to the sensor, now I will have to figure out what IC to use to feed the LED bargraph.

Werewolf Wu, good job on the explanations. I am also pleased that I am not the only one who hates it when manufacturers and individuals fail to follow the rules for upper and lower case letters when showing metric values. I even worked with a company for several years where the engineers knew better, but the company 'hard rule' was that all printing on drawings and stamped onto products MUST be in upper case, so milli always became mega, etc.

@@ChristianGrau92 Hello! Sorry for the late reply. There are only two wires connected to the sensor: red and orange. The best way to internalize the working mode of these sensors is to treat them as "smart" resistors, that adjust itself so that the current flowing through them "happens to" scale perfectly with whatever they are sensing. The common arrangement of "red for power black for ground plus some signals" does not apply to these sensors. Hope this helps!

@werewolfwu Жыл бұрын
Hello Diego: if your sensor is a resistive one, it is definitely NOT the same as 4-20mA sensor. You can still use a similar circuit as shown with minimal modification: simply form a resistive divider with your sensor (which is a resistor) and another resistor (say around 100ohms), and sense the divided voltage compared to the reference. This way you get the ratio between the resistors, and hence the resistance value. A little math is needed but not too hard.
