Again the 130Hz drop is consistent. Looking at the Excel spreadsheet, the resposnse almost mimics the …show more content…

Otherwise there is just the overall level of -3.25 dB softer when the lights and aircon are off by looking at the reference level. One technical overview Knowing that the room ambient noise didn’t affect the results too much, it would be interesting to cross correlate the best acoustic dampener configuration – the Slits panel vs the control. Not having software to cross correlate in depth, a simple subtraction between the two responses will be done and then plotted: The average amplitude implies that there is an average of around -1dB per frequency over the spectrum comparing the two configurations. Conclusion Going through these configurations and the final cross correlation it is easy to see that the panels on their own make for the most effective acoustic dampener. However if an overall level drop is needed, the ambient noise needs to be taken down by the source, i.e. the aircon and lights should be switched off. Finally, in all the cases of the interpolation points assuming that the speaker was not struggling to reproduce the 130 Hz, the frequency can be a direct relationship to the distance the microphone was in relationship to the first reflective surface. So about 0.66m or 66cm from the first reflective surface seems to be roughly a good estimate as to how far the sound wave had to travel until it came back to the microphone. Of course this

In 2096, the Earth starts being exhausted of resources, water level rises due to climate change and the increasing radiation from the Sun. During this period, World War III happens with the two opposing sides are China and United States of America who are fighting for the ownership of the very limited resources on Earth. People would kill, steal, and rape others so that they can survive. Most people if not all have already lost their consciousness and sanity. However, a scientist named Sirloc is inventing a machine that hopefully will be able to solve the problem and bring peace back to Earth.

Echo Barrier Case Study

588 Words | 3 Pages

Throughout Canada, increasing use is being made of award winning Echo Sound Barriers to counteract noise pollution. As companies become aware of the advantages of the range of noise reduction solutions available from the Echo Barrier company, the impact of noise on the environment in Canada is reducing. This can only be an advantage to the health and welfare of the nation. Unacceptable levels of sound can come from many sources. Construction and building work, demolition sites, generators, airports and railways and even children playing in the garden can make life unbearable for those who live or work in close proximity.

Soundpost Thesis

1265 Words | 6 Pages

THE EFFECT OF THE SOUNDPOST ON VIOLIN SOUND The sound output and the response of a violin were measured for three positions of the soundpost: no soundpost, inside and outside the treble foot of the bridge. The sound quality was assessed with Long Time Average Spectra that showed small differences. There were significant differences in the response plots, whether measured by a microphone in front of the top or a magnet/coil pickup on the bridge.

Fundamentals Of Sound Oral Scene Analysis

The final acoustic attribute that defines the sine-wave tone is its starting phase. Thit does not mean that this phase is not encoded by the auditory system. As phase differences between the sounds reaching each ear result in differences in perceived location of the sound source. The two sounds differ in frequency, with the sound cycling between periods of higher and lower air pressure at a lower rate, or frequency. These physical properties influence how it is displaced by sound; higher frequencies vibrate the stiffer base to a greater extent than do lower frequencies, creating a place code along the basilar membrane such that different locations are maximally displaced by different sound frequencies.

Advantages And Disadvantages Of Artificial Cochlea

810 Words | 4 Pages

The location of the largest vibration in the basilar membrane depends on the frequency of the travelling wave (Fig 1E). Width, thickness, and stiffness of the basilar membrane vary along the length of the cochlear spiral [2]. Due to this variation in impedance (mechanical), high frequency sounds amplify the motion of the basilar membrane near the base of the cochlea, whereas low frequency sounds amplify its motion near the apex (Fig 1E)

Dylan Garofalo Sound Experiment

A soundwave is made up of many parts such as wavelength, amplitude, crest, and trough. Wavelength is the distance from one crest on the sound wave to another crest on the sound wave. The trough is the lowest point on a sound wave and the crest is the highest point on a wave. Amplitude is the distance from the crest to the trough. All of the pieces that are provided are incredibly essential to the wave as each by themselves creates nothing

Timbre Specificity

1733 Words | 7 Pages

Timbre is the sound quality which differentiates musical notes of identical pitch, loudness and duration played by different instruments. Instruments have their own acoustic properties which generate the differences in listeners’ perceived timbres, and the key to it is the spectral and temporal features of the sound. In the aspect of spectra, most instruments generate harmonic resonances in which they produce energy at multiple numbers of fundamental frequency. These harmonic resonances are very similar to the speech produced by the vibration of vocal chords. Just like the varied vowels, the differed energy patterns across different harmonics determine distinct instrument properties.

So we can reduce that damping by using frictionless strings. We must stop the effect of wind in this practical. So we have to fix this apparatus into a glass box and make that box as a airless box. We must use less weight springs for this practical to avoid errors in calculations because this mass can change the final value. We haven't enough time to observe the correct value of amplitude.

Aerodynamic Analysis Of Voice: Aeroic Analysis

2199 Words | 9 Pages

Aerodynamic analysis of voice includes static measures of respiration and dynamic measures of laryngeal valving. The static measures help in understanding the volumes of air that can be inhaled / exhaled in a breath and maximum capacities of an individual’s respiratory system. The dynamic measures provide information about the efficiency of laryngeal valving in converting the expiratory airstream to acoustic energy. Dynamic measures that aid in assessing efficiency of laryngeal valving comprise majorly of the measures of pressure variations at the level of glottis and airflow through the glottis during phonation.

Speech Waveform Characteristics

This device produces a two-dimensional pattern called a spectrogram in which the vertical dimension corresponds to frequency and horizontal dimension to time. The 16 bit gray scale level is used to represent the given spectrogram. Even though the colour representation is more visually appealing, it sometimes leads to misleading interpretation of the spectrogram. The darkness of the pattern is proportional to signal energy. Thus, the resonance frequencies of the vocal tract show up as dark bands in the spectrogram .Voiced
