This is the sound the spider hears when its prey falls into the web. Scientists at the Massachusetts Institute of Technology have turned fabric vibrations into music.
Among the wonders that animals are capable of, the spider web is usually the highest ranked.some Spider silk They are stronger than steel of the same thickness, and their purpose is to capture prey without having to spend a lot of energy on hunting. Spiders can feel the impact and struggle of their prey through the vibrations transmitted by the lines of the web.
Now, scientists at the Massachusetts Institute of Technology convert the different frequencies of network threads into music when they vibrate, because the prey falls into the network.
Spiders are mostly blind, but their webs are very sensitive to interference detected with their legs. Now, scientists have created an audiovisual version of virtual reality, which converts the vibration of the web into sounds we can hear, giving us an understanding of the extraordinary composition of sounds that spiders can feel.
Markus Buehler of the Massachusetts Institute of Technology presented this work at a virtual conference. American Chemical Society.
The spider uses its network to send messages
Because the length and tension of each line of the web are different, they will emit different frequencies when they are disturbed, and they can even be used to send signals or communicate with other spiders.
Buehler’s team used laser images to create a 3D map of the web made by tropical spiders ( Lemon Algae ). They determined the vibration frequency of each wire through its size and elasticity, and then converted these frequencies into other frequencies that humans can hear.
By putting the visual and auditory layers together, users can connect sounds to the strings they see, mimicking spiders’ observations of their world.
The team made some artistic decisions, such as using a synthesizer with a harp-like sound.
Sounds that are closer to the listener or connected to many other strings are louder than those that are farther away or less connected. For Buehler, who spent hours listening to the noise generated by virtual networks, they are no longer just sound dissonances, but start to have recognizable structures.
