Music, brain and learning

Teaching courses in music and psychology

The purpose of the course is to investigate the influence of music on pupils' ability to solve cognitive-based tasks - including the students emotional experience of it and knowledge of its structure has an impact on the outcome. Students thus gain knowledge about how their musical skills can be used as learning tools in other subjects. In psychology, the cognitive results can form the basis for inspiration for later experimental work, eg in psychology B / C on stx or Internal Assessment for 2nd year IB students.

Sound, ear and evolution

Teaching courses in biology

Focus in the process is the development, application and importance of sound, hearing and music in humans compared with whales and dolphins. The starting point is the team's experience in the audio universe, and the course develops from there to work with sound in several different levels and ways. The course is part of a larger coherent course of evolution, nerves and hormones. The "sound course" covers the anatomy of the ear and the impact of music on memory, learning and stress.

Binaural recording technique

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:

The Virtual Hairdresser

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.

Determining Direction of Sound

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.

Where Does the Lion Come From?

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

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.

The Boundary Effect
Where Should Your Speaker Be Placed?

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.

What is reverb?

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.

WHERE AM I?

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.

The Loudspeaker

Acoustician Villy Hansen explains in the information videos how a loudspeaker unit works, why the unit sits in a cabinet, why most loudspeakers consist of multiple units, and what the advantage of an active rather than a passive loudspeaker is. In the last four videos, history expert Ronny Kaas tells about the loudspeaker’s history and shows examples of different types of speakers.

How Does a Loudspeaker Work?

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.

The ear

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.

About The Sound Universe 2.0

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.
