Is it possible to create a situation in which there is only destructive interference? Explain.
When two waves interfere constructively or destructively, is there any gain or loss in energy in the system of the waves? Explain.
A train sounds its horn as it approaches an intersection. The horn can just be heard at a level of 50 dB by an observer 10 km away, (a) What is the average power generated by the horn? (b) What intensity level of the horn's sound is observed by someone waiting at an intersection 50 in from (lie train? Treat the horn as a point source and neglect any absorption of sound by the air.
In Example 18.1, we investigated an oscillator at 1.3kHz driving two identical side-by-side speakers. We found that a listener at point O hears sound with maximum intensity, whereas a listener at point P hears a minimum. What is the intensity at P? (a) less than hut dose to the intensity at O (b) half the intensity at O (c) very low but not zero (d) zero (e) indeterminate
Jack and Jill go for a walk along an abandoned railroad track. Jack puts one ear next to a rail, while Jill, 200 m away, taps on the rail with a stone (Figure 6.55). How much sooner does Jack hear the sound through the steel rail than through the air?
How can you determine that the speed of sound is the same for all frequencies by listening to a band orchestra?
71. •Two identical speakers (1 and 2) are playing a tone with a frequency of 171.5 Hz, in phase (Figure 13-42). The speakers are located 6 m apart. Determine what points (A, B, C, D, or E, all separated by 1 m) will experience constructive interference along the line that is 6 m in front of the speakers. Point A is directly in front of speaker 1. The speed of sound is 343 m/s for this problem. SSM 6 m 6 m ABCDE Figure 13-42 Problem 71 2.
Question:- (1) Write three important boundary conditions the wave should obey at variable linear mass density interfaces/ boundaries. (ii) Derive reflected and transmitted wave amplitudes in terms of incident wave amplitude.
1-) Humans can roughly hear frequencies between 20 and 20,000 Hz, what is the range of wavelengths that are audible to humans in air (convert the frequency range to wavelength)? The visible range of light is considered light that ahs a wavelength between 400 and 700 nm, What is the visible frequency range of light (convert this wavelength range to frequency). Use speed of sound as 344 m/s in ai for the above calcualtions 2-) An interesting method to remove brain tumor involves using an ultrasonic surgical aspirator, which produces sound waves with frequency 23k Hz. (a) What is the wavelength of this sound in air? When this device is used on tissue the medium the sound travels in is no longer in air, but instead is bodily tissue and fluids, where the speed of sound is roughly 1480 m/s, what is the wavelength of the sound in this medium (frequency is unchanged).
Mel Frequency Cepstral Coefficients (MFCC)s are widely used for the recognition of speech. TheseMFCCs help to highlight some of the important qualities that are present in speech that can helpdifferentiate speakers and individual words. The computation of MFCCs can be typically split into thefollowing steps:1. Windowing2. Discrete Fourier Transform (DFT)3. Filter Bank and Logarithmic Computations4. Discrete Cosine Transform (DCT)The aim of this homework is for these stages to be investigated, described, implemented, appliedand comparisons performed between different settings.You will need to research this well known topic and understand how Matlab can be used to performthe various steps outlined above. The system should be implemented in Matlab and used to process the speech data. Also mathematical expression of each stages of the above should be included.
