happy and sad music. Ambient noise can improve creativity: It turns out that a moderate noise level is the sweet spot for creativity. Happy/sad music affects how we see neutral faces: We can usually pick if a piece of music is particularly happy or sad‚ but this isn’t just a subjective idea that comes from how it makes us feel. Even more than low noise levels‚ ambient noise apparently gets our creative juices flowing‚ and doesn’t put us off the way high levels of noise do. Our music choices can predict

The effects of population density and noise The effects of Population Density and Noise Noise and Population density has several different affects on individual’s Personal space‚ Privacy‚ and territory may have negative affects on individual‚ along with chronic noise. Population density and noise can have a variety of effects on people. The effects vary by individual but can lead to anxiety‚ increased stress levels‚ aggravation and more. As the population increases awareness of personal

retransmission protocols amplify and forward (AAF) and decode and forward (DAF) are implemented at the relays and four diversity combining techniques such as equal ratio combining (ERC)‚fixed ratio combining (FRC)‚ signal to noise ratio combining (SNRC) and equal signal to noise ratio combining (ESNRC) are used at the destination for each protocol. The performance of single relay system is compared with the performance of direct transmission and transmission through single relay system. single-relay

modest amounts of background noise or reverberation (i.e.‚ many delayed reflections of the original sound) can interfere with speech perception and‚ consequently‚ can impair educational outcomes. Speech intelligibility studies indicate that students’ ability to recognize speech sounds is reduced for younger children. This problem is frequently not appreciated by adults‚ who are better able to recognize speech in the presence of noise. Research has shown that noise exposure affects educational outcomes

conditional entropy for a noiseless binary channel. 3. A telephone line channel has a bandwidth of 3 kHz and a S/N = 1500 at the channel output. Calculate the channel capacity in bits/sec. 4. A Gaussian channel has a bandwidth of 4 kHz and two-sided noise power spectral density N0/2 of 10-14 Watt/Hz. The signal power at the receiver has to be maintained at a level of 0.1 milliWatt. Calculate the capacity of this channel. 5. Given a Gaussian channel with a bandwidth of 1 MHz and SNR of 30 dB.

Recently‚ big cities such as Tokyo‚ Beijing‚ and Shanghai suffer from serious air and noise pollution because of the volume of passenger cars. Although passenger cars are one of the most convenient vehicles for residents‚ the governments should ban passenger cars because the volume of passenger cars cause environmental issues‚ health problems of citizens‚ and fearful effects on transport of emergency vehicle. First‚ although the unit sales of eco-friendly cars is increasing in big cities‚ there

An Assessment on the Effects of Television on the Youth Research Background Television is invented for the purpose of sharing the information‚ and if not‚ at least for the entertainment. The family who use has a ritual in sitting in front of television while watching television might share their point of views but can affect the appetite of the children. The viewers that can be more affected by watching television are the children or youth. This is commonly noticed while the children or youth are

freedom were then calculated and an appropriate orthogonal array (L9) was then chosen. After performing 4 trials for each combination given in the L9 orthogonal array‚ the results were interpreted using Minitab. The corresponding Means and Signal to Noise ratio were found and plotted in Minitab. ANOVA tables were also made in Minitab to see which factors affect the results more and which ones can be seen as just an error. From the signal to ratio plots I was able to determine which combination would
