An example of intensity is having the ability to run miles on end at a top speed. An example of intensity is how quickly a treadmill is moving. Saturation. Degree or extent; relative strength, magnitude, vigor, etc.

Speculate is to buy or sell land or other investments that are high risk, with the goal to make a very big profit. An example of speculate is to buy land way out in the country to build housing because you hear that a new manufacturing plant might be built close buy.

Spectacle Sentence Examples You’re making a spectacle of yourself. While Dean enjoyed the spectacle of the exciting contest, he harbored no envy toward its participants. As his plays show, the spectacle struck Antonio’s observation, but he had to criticize with caution.

make a spectacle of (oneself) To attract attention by foolish or conspicuous behavior. Darren’s so clumsy that he tends to make a spectacle of himself everywhere he goes.

1 : the quality or state of being intense especially : extreme degree of strength, force, energy, or feeling. 2 : the magnitude of a quantity (such as force or energy) per unit (as of area, charge, mass, or time)

a high or extreme degree, as of cold or heat. 4. the degree or extent to which something is intense. 5. a high degree of emotional excitement; depth of feeling.

Things to remember You can measure exercise intensity using target heart rates, the talk test, or the exertion rating scale. For maximum health benefits, the goal is to work hard, but not too hard, described as moderate intensity by Australia’s Physical Activity and Sedentary Behaviour Guidelines.

All activities, based on intensity, can be placed into the five categories of the Five for Life Activity Diamond, a tool used to distinguish intensity levels during physical activity. The five categories are Media/Seat, Daily Activity, Base, Heart Health and Max.

Instead we define intensity I as the power of light going through a unit area (in other words, intensity is the amount of energy that arrives per unit area, per unit time). The more intense the light reaching us is, the “brighter” the light appears to be.

Noun. 1. intensity level – the amount of energy transmitted (as by acoustic or electromagnetic radiation); “he adjusted the intensity of the sound”; “they measured the station’s signal strength” intensity, strength.

Thus, sound intensity levels in decibels fit your experience better than intensities in watts per meter squared. For example, a 90 dB sound compared with a 60 dB sound is 30 dB greater, or three factors of 10 (that is, 103 times) as intense.

The intensity of a sound is the power of the sound in Watts divided by the area the sound covers in square meters. The loudness of a sound relates the intensity of any given sound to the intensity at the threshold of hearing. It is measured in decibels (dB).

Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. Sound intensity level is a logarithmic expression of sound intensity relative to a reference intensity.

The most desirable intensity of sound to support a normal conversation is between 30-60 decibels. Hence, we can say that the intensity of sound between 30-60 decibels is the intensity for a normal conversation.

decibels

if you consider light is wave, intensity is related to light radiation energy and frequency is the number of waves per second. Frequency is related to photon’s energy (E = hν , E is energy, h is planck’s constant and ν is frequency) . In particle nature, intensity is related to number of photons in the radiation.

Each factor of 10 in intensity corresponds to 10 dB. For example, a 90 dB sound compared with a 60 dB sound is 30 dB greater, or three factors of 10 (that is, 103 times) as intense. Another example is that if one sound is 107 as intense as another, it is 70 dB higher.

Frequency has a major effect on how loud a sound seems. Sounds near the high- and low-frequency extremes of the hearing range seem even less loud, because the ear is less sensitive at those frequencies.

The area of a surface around a point sound source increases with the square of the distance from the source. This means that the same sound energy from the source is distributed over a larger area and the energy intensity reduces with the square of the distance from the source (Inverse Square Law).

Decibels measure sound intensity Frequency, reported in Hertz (Hz), measures the number of sound vibrations in one second. Amplitude, reported on the decibel (dB) scale, measures its pressure or forcefulness. The more amplitude a sound has, the louder it is.

68 db

What’s too loud? too high. Sound is measured in decibels (dB). For reference, normal breathing is about 10 dB, a whisper or rustling leaves 20 dB, and conversation at home are around 50 dB.

The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.

Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.

The loudness of sounds is measured in decibels (dB)….Decibels Explained.

between 60 and 85 decibels

100 – 120 decibels: For example, a bulldozer, impact wrench, or motorcycle. 120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail. 125 – 155 decibels: Like, firecrackers or fireworks, or a jet engine.
