the hearing process. Harvey Fletcher and Wilden Munson revealed‚ among other things‚ that the human ear is not linear‚ and is not capable of detecting all frequencies equally at all sound levels‚ which has come to be known as the Fletcher-Munson Curves‚ or equal loudness contours. Harvey Fletcher and Wilden Munson discovered that our hearing is decidedly nonlinear with respect to frequency and perceived loudness‚ and they mapped this data at various the two researchers asked subjects to compare

The Implications Of Learning Curve 1) What are learning curves? The learning curve is a successful story for cognitive psychology‚which has provided a rough trend on the process of trainees’ learning development The notion of a curve is based on the recognition that there is a relationship between the rate of learning and the passage of time. Managers working on the introduction of a new system‚for example‚might say‘we are on a learning curve’. When it comes to the adaptive training‚ the

the demand curve? To show what the consumer should do to maximize utility‚ a budget line must be added to the preferences shown in the indifference curves. The picture below adds one. Point a is not attainable because it lies to the right of the budget line. The consumer is indifferent between points b and d because they lie on the same indifference curve‚ but point d is cheaper than b because d lies below the budget line. The consumer wants to get on the highest indifference curve affordable

The economy could choose to operate at less than capacity somewhere inside the curve‚ for example at point a‚ but such a combination of goods would be less than what the economy is capable of producing.

Why the aggregate demand curve slopes downward: To answer this question‚ we recall that the components of economy’s GDP: Y = C + I + G + NX We assume that government spending is fixed. The other three components: consumption‚ investment‚ and net exports depend on economic conditions and on the price level. 1. The price level and consumption: The wealth effect: Ex: The nominal value of a dollar is fixed‚ yet‚ the real value of a dollar is not fixed. Coca Pizza 1 $ 1 0.5$ 2 → A decrease

The Phillips Curve and the Philippines According to Cristeta B. Bagsic‚ the Phillips Curve “depicts the trade-off between inflation and unemployment rate” (“The Phillips Curve and Inflation Forecasting: The Case of the Philippines”). Nowadays‚ the relationship depicted by the Phillips curve is specified in the following equation: πt = πe – γ(UR – UR*) + v where πt is the inflation rate‚ πe is the expected inflation‚ γ is a parameter‚ UR is the unemployment rate‚ UR* is the natural rate of unemployment
