Welcome to the education page. Here you can find educational programs for free use by teachers from Struer Statsgymnasium in the subjects physics, biology and music / psychology. All learning material has been tested and adjusted. Enjoy.
You have now experienced having your hair cut with sound. The sound in The Virtual Hairdresser is an example of how your brain can create a sense of spatiality with the help of your ears solely. You can acquire further knowledge about the binaural technique behind the sound in The Virtual Hairdresser and its use in the information videos:
Welcome to the first station in Sound universe 2.0. Here you can have your hair cut – with sound. You have to put on headphones and start the experiment on the play button in the player to the right. The sound in The Virtual Hairdresser is created using the binaural recording technique. You can learn more about binaural sound if you click on the arrow in the bottom left corner.
If you hear a sound to your left, the sound will reach your left ear first and then your right ear with a slight delay. Additionally, there will be a slight difference in terms of volume. This is what your brain uses to determine where the sound comes from. The experiment, which you have just done, focusses on this. The different placements of the roars of the lion in the experiment on this page are made by using the binaural recording technique, which uses delay between the right and the left ear and different volumes to create a feeling of spatiality. In the videos, you can find more information about horizontal and vertical locating ability and about the cocktail party effect.
In this experiment, you have to guess where the roar of the lion comes from. There are nine rounds and you have nine possible answers for each round - click on the speaker you think the sound is coming from. Remember to turn the headphones correctly. If you click on the arrow in the left corner, you will be able to learn more about how and why people can determine direction of sound.
The boundary effect boosts the speaker’s deep frequencies if you place it against a wall or in a corner – instead of placing it free-standing in the room. In the experiment you have just tried, the differences between the speaker’s sounds are made on a computer. When you move the speaker to a corner in the experiment, the bass frequencies are boosted from 0 to around 300 hertz, and the experiment is constructed to allow you and the other users of The Sound Universe to clearly hear the bass become more powerful. In reality, the deep frequencies will be experienced as being up to three times more powerful when a speaker is placed in a corner compared to when it is placed in the middle of the room.
Try moving the speaker into the corner and hear what happens with the sound. What you are experiencing is a simulated example of the so-called ‘boundary effect’. If you click on the arrow in the left corner, you can learn more about the boundary effect.
In the first of the dissemination videos you can hear acoustic Villy Hansen explain what vocal really is. In the three following videos he gives examples of how different rooms affect sound. You can also hear sound engineer Jørgen Lindholm tell you how acoustics include is in the theater hall in the music theater Holstebro, and how to manipulate the sound in the hall using artificial sound and different effects. Enjoy.
In this experiment, try to determine where the person in the audio clips is located. All you have to do is how the room affects the person's voice - so you need to listen carefully. There are 12 rounds in total and you get 4 answers for each audio clip. You can learn more about rumbling if you click the down arrow in the left hand corner of the screen.
In the picture in the upper right corner, you see a cabinet with three loudspeaker units. You can see the units’ membranes move in and out when you turn the bass-, intermediate tone- or the treble frequencies up and down. In reality, the oscillations are a lot faster. If you click on the arrow in the left corner, you can learn much more about how the loudspeaker works.
To the right you can see a cross section of the human ear. You can click on the different elements in your ear and get to know what they are called. The hammer, the anvil and the stirrup sit in what is called the middle ear. The middle ear is one of the three areas in which the ear is divided - the other two are the outer ear and the inner ear. Below you can hear acoustic Villy Hansen tell about each area.
Click through the fascinating tale of the creation of the human's three smallest bones - the hammer, the stirrup and the anvil. The three bones are all in the middle ear and together form a central part of the human hearing. You can learn much more about the middle ear and the outer and inner ear if you click the down arrow on the left side of the screen.
On this page, acoustic Villy Hansen expands some of the areas mentioned in the video on the previous page. In addition, he gives an idea of how the future's experience design will be. If you'd like to know more about binaural sound, which is also mentioned in the video, click on menu and then on 'Binaural Sound'.
Here you can become more aware of how the reproduction of sound has evolved from the latter half of the 19th century and towards today's extremely natural sound reproduction. The technological and acoustic landmarks mentioned in the video can help you learn more if you click the arrow in the left corner.
In the first two dissemination videos, lecturer Jesper Nørgaard tells about frequency, amplitude and harmonics. In the final video, sound expert Mathias Lyhne explains what ultrasound is and how specific species are oriented using these high frequency signals.
If you click on one of the instruments, you can hear it play a tone. At the same time you can see two different images of the sound, one showing frequency / amplitude and the second time / amplitude. If you click on the youtube icon, you can see the larger-sized images. You can get more knowledge of frequency, amplitude, human hearing and ultrasound, if you touch the arrow in the left corner.
The experiment you have just tried focuses on how the sound for the short animation is created. Henrik Gugge Garnov is executive manager, co-owner and sound director at the sound production company Gilyd, and in the three videos on this page he explains what foley means, what a foley artist does, and how he handles his various tasks.
When you press play, you'll see a bite of a cartoon. Each movie clip hears a question that you must answer after watching the clip. Therefore, listen carefully. After the experiment, you can click the arrow in the left corner and learn more about what foley is and how to make audio for movies and shows.
The Sound Universe 2.0 is created by Struer Museum in collaboration with Struer Statsgymnasium. The experiments, the information videos, and the overall idea for this website is borrowed from a permanent exhibit at Struer Museum, which is (also) called The Sound Universe. During the transformation from physical exhibition to digital learning platform, new information videos have been added and the experiments have been adjusted to fit the new medium. Teaching materials have been developed by teachers at Struer Statsgymnasium. All teaching material has been tested and adjusted. The Sound Universe 2.0-project has received funds from Region Midtjylland and the department of City of Sound at Struer Municipality.
