	Propagation of sound in water Principle The aim of this experiment is to enable the students to find out that sound can also propagate in other media, e.g. liquids. For this purpose, they study the propagation of the sound of a tuning fork in a tube that can be filled with air or water. For ...

	Sound as a sine wave Principle The aim of this experiment is to familiarise the students with the "measure Acoustics" software. First, the students record the sounds of two tuning forks with a microphone. Then, they analyse the frequency spectrum and the course of the amplitude of ...

Product-No: P6010400

	Sound and noise Principle Oscillations can be transferred through a medium (e.g. air or wood) in the form of sound waves. An oscillation with exactly one oscillation frequency is called harmonic oscillation or pure oscillation. In the amplitude-time-diagram, such an oscillatio ...

	Lower and upper hearing threshold Principle The human ear registers deep and high sounds as well as faint and loud sounds. Are there limits or can we hear any kind of high and deep sounds? In this experiment, the students learn that the human ear can perceive sound only within a limited frequen ...

	Directional hearing Principle The human sense of hearing is not only used to perceive sound, it even enables us to localise the direction from which we hear sound signals. On the horizontal plane of orientation (left/right, front/back) as well as on the vertical plane of orientati ...

	Harmonic Oscillation Principle Sound waves are usually produced in locations where a medium, e.g. air, is compressed and then allowed to expand again. Sounds are caused by repetitive movements, called oscillations. The aim of this experiment is to familiarise the students with the ...

	Visualization of the vibrations of a tuning fork Principle In this experiment, the students visualise the oscillations of tuning forks by plotting the oscillations of a pen-equipped tuning fork on a sheet of paper. They see that the sine curve is the course of an oscillation over time, and they compare the f ...

	Beat frequency Principle If several sound signals reach our ears simultaneously, these signals superpose, thus forming a resulting signal. If the individual signals all have the same frequency, the resulting signal can also be heard with this frequency. The volume, however, ...

	Measurement of sound velocity Principle In this experiment, the students determine the velocity of sound in air. For this purpose, they measure the difference in the propagation time of a sound signal of two spatially offset stereo loudspeakers with the "measure Acoustics" software. ...

	Reflection and echo Principle In this experiment, the students observe the reflection of sound pulses in a glass tube - with a sealed and also with an open end. They record the signal and echo with a microphone and analyse the differences in the propagation time with the "measure ...

Product-No: P6011200

	Standing waves Principle When the sound wave of a sound propagates in air, this wave causes all of the air particles that it reaches to oscillate. If the sound is generated continuously, all of the particles are constantly in motion. In this experiment, the students observe t ...

Product-No: P6011300

	Resonance Principle There are so-called resonance boxes for tuning forks that can increase the sound volume of the tuning forks to a considerable extent. A resonance box is a hollow body with certain dimensions and it is usually made of wood or metal. Resonance boxes, or ...

Product-No: P6011400

	Bone conduction Principle In this experiment, the students can observe that sound can reach the inner ear not only via the outer and middle ear but also via the human bones. In medicine, bone conduction is used for diagnostic purposes. Based on the Rinne and Weber tests, which ...

	Noise level traffic lights Principle Noise is very disturbing for a lot of people. Sometimes, however, we do not realise how loud it is around us because we are busy with other things. In these cases, our feeling of loudness is dulled and we do not notice how much the noise actually impa ...

	Scales and intervals Principle Scales consist of notes of different pitches. The C major scale can be played perfectly on a piano since it requires only the white keys. On a string instrument (e.g. a violin) the pitch is determined by the length of the string. The distances between ...
