It was only during the second half of the Bush administration that Robyn Rihanna Fenty was scooped up by producer Evan Rogers and subsequently introduced to Def Jam CEO Jay-Z, who signed her to the label hours after her first audition. Achieving multi-platinum status the world over, Good Girl Gone Bad remains one the decade’s best pop collections, spinning off five massive hits and solidifying the young Barbados-born singer as one of the brightest of her ilk. To her credit, Rihanna probably knew that Rated R would suffer to escape the shadow of her comeback from the Brown affair, which is one plausible reason that recording sessions for Loud began just a few months after the former was released. What she and her producers fail to understand, though, is that the public wants those coital waves to come crashing down, blanketing the earth in the seduction of Rihanna’s natural, Caribbean appeal. But this is this era of the single, so I suppose we should consider ourselves lucky that Loud is mostly great. At 83 years old, the queen of country music gifts listeners another album of heartfelt zingers. Sia Furler’s collection of tunes other pop stars turned down will make you question their judgment.
These are among the best phonics worksheets, games, videos and flash cards you will find online. The basic qualities of the sounds we are surrounded by everyday - high pitched, low pitched, loud, and soft - are determined by the frequency (the number of cycles per second) and the amplitude of the waveforms of those sounds. In the case of a drum set, for example, the large bass drum produces a lower pitch than the smaller snare drum.
The unit used to describe frequency, or the number of cycles per second, is the "Hertz," abbreviated as "Hz." A waveform in which only one complete cycle occurs per second has a frequency of 1 Hz, ten cycles per second is 10 Hz, 100 cycles per second is 100 Hz, and so on. The frequencies are arbitrary and vary a bit, but the range from 20 Hz to about 250 Hz is generally considered to be the low frequency range. Another interesting characteristic of human hearing is that as pitch gets higher it becomes easier for us to determine the direction from which the sound is coming. The softest sound detectable by the human ear is defined as 0 dB, but of course there are individual differences. In addition to the characteristics of pitch and loudness that we've discussed thus far, sound also has "timbre" caused by variations in the shape of the waveform. We started out with a bit of basic theory that is necessary in order to understand the terms "frequency (Hz)" and "sound pressure level (dB,)" both of which will appear frequently in the text that follows. While an occasional 110-dB concert may only do minor hearing damage, a steady weekly diet of such levels can be devastating to the hearing of both the musicians and the congregation. Note on the exposure chart below the sidebar how high an SPL a person can tolerate per day before hearing loss begins.
That 110-dB SPL mix in your church is going to start destroying hearing within the first 30 minutes (or sooner) of your music service.

And that doesn’t even take into account the hours of practice your band has been doing at that volume level. No wonder your ears (and everyone else’s in your congregation) are ringing by the end of the service. You can do a great rock mix at around 95 dB SPL (which is safe for up to 4 hours a day exposure) if you have control over the volume of the stage instruments such as electric guitar, bass and drums.
But without having the stage amps playing at a reasonable level to begin with (less than 85-dB SPL in the room) you’ll never be able to do a solid 95-dB SPL mix in the room. The chart to the left is produced by the US National Institute for Occupational Safety and Health (NIOSH) uses a more protective exchange rate which results in shorter allowable exposures at high SPL’s levels than the OSHA regulation.
While questions regarding the calculation of exposure time are prime subjects for another article, mor information cal always be found on the websites of OSHA, NIOSH, and the House Ear Institute. In the end, when dealing with loud volumes and competing standards, common sense, good judgement, and strict control of a master fader are your best weapon.

Keeping it as brief and as simple as possible, we'll explain the basics you need for a full understand of the content that follows. One complete "round trip" of the waveform - up from zero, then down to below zero, and back up to zero again - corresponds to one "cycle" of the waveform. Generally, the larger the vibrating element of a musical instrument, whether it's a larger drum head or a longer piano string or a longer column of air in a wind instrument, the lower the pitch.
Within this range frequencies below about 80 Hz are considered to be ultra-low frequencies. We are very sensitive to differences in the loudness of soft sounds, but as the sound gets louder it becomes more difficult to differentiate between small changes in loudness.

Now that we've covered the basics of sound, let's take a look at sound systems and the individual components that they are made up of.
Basically, the safe bet is that if it seems too loud to a seasoned professional, it is too loud. Written by professionals for professionals, each issue delivers essential information on the latest products specs, technologies, practices and theory.
Those missteps are more stylistic than anything else, seemingly situated in calculated fashion to offset the sexual, flustered tension scurrying all around them.
Eminem)” follows the script of Part I closely, a melancholy acoustic arrangement sitting atop one big blown out beat. The genre-hopping missteps certainly hurt, but overall, Loud is exactly the record Rihanna needed to make right now.
That vibration is transmitted directly to the surrounding air, pushing and pulling it as the drum head moves alternately inward and outward.
There are individual differences, but the normal range of human hearing is from about 20 Hz to 20,000 Hz (20 kHz). The midrange frequencies extend from 250 Hz up to around 4,000 Hz, and this band is sometimes further sub-divided into low-mid, mid, and high-mid bands.
The harder you beat a drum, for example, the greater the amplitude of its physical vibration and thus the greater the amplitude of the waveform transmitted through the air. At the other end of the scale, the loudest sound that the human ear can handle for short periods without discomfort and possibly damage is around 120 dB. Indeed, unlike the hack sexiness of Katy Perry and Ke$ha, the sensuality and compassion on Loud is believable, plenty so to make us forget about her all too public misfortunes. That vibration causes variations in the density of the air that travel away from the drum head like waves. This is what is referred to as "sound waves." When the sound waves reach our ears they impinge on our eardrums and cause them to vibrate correspondingly, and then our nervous system and brain take over to translate those vibrations into perceived sound. Everything above 4,000 Hz is the high frequency band, also sometimes subdivided for even finer control.
