In what units do we measure the loudness or intensity of sound? This is a logarithmic scale, why is this type of scale used? Loudness The loudness of sound tends to how much energy a particular sound wave carrie
Ampeater Music is a website devoted to bridging the gap between unsigned (or just plain underexposed) artists and music lovers everywhere. Every day we feature a different artist on what we call The Ampeater Review. Each fea
What is the number of the highest harmonic that could be heard by a person who is capable of hearing frequencies up to 1.00 {eq}\times {/eq} 10{eq}^4 {/eq} Hz? Frequency Frequency is defined as the number of waves that pass t...
Introduction of a grating or noise had no in- fluence on the average luminance, which was 7 cd m-2• Contrast could be varied in l-dB (.OS-log-unit) steps using precision atten- uators. PrCK:edure In all experiments, a two-alternative, forced-choice procedure was used to determine...
Another analogy of course is the speaker. The ideal speaker has no stored energy. It's movement at any moment of time is 100% determined by the instantaneous voltage at the inputs with no "memory" of what has happened before or "precognition" of what may come after. As you probably ...
“What is in the middle?”, you and I would choose five objects, but the average Amazonian will choose three. When thinking in terms of ratios and logarithmic scales (rather than differences and linear scales), one times three is three, and three times three is nine, so three is in ...
The quote “You are the average of the five people you spend the most time with” is often attributed to motivational speaker Jim Rohn. If true, then I’ll ask if those five individuals are lifting you up, keeping you at a mediocre level, or dragging you down from your greater ...
These were recitals for the residents of aged care facilities. The average age of the audience was 87 and one could not wish for a more appreciative audience. Everyone was happy and excited to be there. This is very different to the performances of my youth, as there were no adjudicators...
That thing is totally awesome for surfing the web, but I can't for the life of me type on it. It's like when I try to text people, just never works out. So do you have any good tips on buying a portable full size keyboard that's pretty easy to travel with? Any input appreciat...
Sound level is a measure of the intensity of sound or acoustic energy in logarithmic units called decibels (dB). It is a dimensionless quantity that compares the sound pressure level to a reference value, typically the threshold of human hearing. Sound ...
