The sound of a man shouting at the top of his lungs from a rather large distance away from your ear has loudness of only 20 decibels. What would be the decibel level of four men shouting at the top of their (equally powerful) lungs from the same distance away from your ear? Assume that there is no interference from superposed waves and round off your answer to the nearest integer. 1. 160 dB 2. 80 dB 3. 60 dB 4. 10 dB 5. 14 dB 6. 6 dB 7. 20 dB 8. 40 dB

26dB

Explanation:

The decibel level β is a calculated by 10log (I/Io)

Where I and Io represent sound intensity

From the question, there's no interference. So

Where I = 4Io (because there are 4 men shouting), so the intensity will be 4 times larger.

β = 10log (I/Io)

β = 10log (4Io/Io)

β = 10log 4

β = 6.020599913279623

β = 6 Approximated

The decibel level = 20 + 6.020599913279623

Decibel Level = 26.020599913279623

Decibel level =26dB --- Approximated

low context culture   (lc.):

association:    

relationships begin and end quickly. many people can be inside one's circle; circle's boundary is not clear.

things get done by following procedures and paying attention to the goal.

one's identity is rooted in oneself and one's accomplishments.

social structure is decentralized; responsibility goes further down (is not concentrated at the top).

interaction:

low use of nonverbal elements. message is carried more by words than by nonverbal means.

verbal message is explicit. context is less important than words.

verbal message is direct; one spells things out exactly.

communication is seen as a way of exchanging information, ideas, and opinions.  

disagreement is depersonalized. one withdraws from conflict with another and gets on with the task. focus is on rational solutions, not personal ones. one can be explicit about another's bothersome behavior.

territoriality:

space is compartmentalized and privately owned; privacy is important, so people are farther apart.

temporality:

things are scheduled to be done at particular times, one thing at a time. what is important is that activity is done efficiently.

change is fast. one can make change and see immediate results.

time is a commodity to be spent or saved. one’s time is one’s own.

learning:

reality is fragmented and compartmentalized. one source of information is used to develop knowledge. thinking is inductive, proceeds from specific to general. focus is on detail.

learning occurs by following explicit directions and explanations of others.

an individual orientation is preferred for learning and problem solving.

speed is valued. how efficiently something is learned is important.
