Human Performance - Assignment Example

This was basically used in the experiment as the components are easy to control and manipulate due to the less number of parameters. Also, the various parameters that will be controlled are as follows. Firstly, the damping time constant where there is an amplitude drop of half of the height. Secondly, the period length and finally the signal level attenuation. It is essential to also note that the single level attenuation is dependent on the total number of uses of the periods. The main reason for the use of ‘dampened sinusoids’ rather than the sinusoids that have been used in previous research is the following.

The dampened sinusoids have been noted to be similar to the single pulse resonance sounds. This has been used in the past for communication by a number of animals and thus it plays a very important role in this research. Since the sound of the single dampened sinusoid is similar to that of one cycle of a vowel, thus the close resemblance to the natural sounds has been used in the research. The benefits of it are numerous and it has been noted that the control is also relatively easier. It will also be interesting to note that this is the only study which used stimuli with a wavelength shorter than one period and also with an increased length in the scale of the logarithm, with almost sixteen periods of the wavelength.
