- n. The act or process of making slender, thin, or lean; the state of being thin; emaciation; reduced thickness or proportions.
- n. The act of making fine by comminution or attrition.
- n. The act or process of lessening in complexity or intensity; reduction of force, strength, or energy; specifically, in homeopathy, the reduction of the active principle of medicines to minute or infinitesimal doses.
- n. The act of making thin or thinner, as a fluid, or the state of being thin or thinned; diminution of density or viscidity: as, the attenuation of the humors; specifically, in brewing and distilling, the thinning or clarifying of saccharine worts by the conversion of the sugar into alcohol and carbonic acid.
- n. In electricity: The decrease of telephonic currents with increasing distance, due to the absorption of current by the electrostatic capacity of the telephone line.
- n. More generally, the decrease of electrical effects with increasing distance.

Jobs kept using the word attenuation which is incorrect because with detuning the antenna comes pattern changes as the system interacts with human limbs now connected to it.
Nicotine-replacement treatments resulted in attenuation of post-cessation weight gain (-0.45 kg) at the end of treatment and at 12 months (-0.42 kg).
Apple conceded the point, but said this effect, called attenuation, occurred on all cellphones, even those whose antennas were out of view inside the case.
What can happen – and this really only applies to longer cable runs of 6 feet or more – is something called signal attenuation, which is a weakening of the electrical signals.
In 1995, 60 percent of our ground water cleanup decisions reflect extraction and treatment being used in conjunction with other techniques, such as bioremediation, underground treatment walls, or monitored natural attenuation, which is often used to reduce low levels of contaminants.
In this only lies the difference between the old word fermentation, and the new word attenuation, every thing used as a ferment, or to promote fermentation, is attenuant.
The next limitation was that certain analog frequencies would transmit more efficiently than one another, causing an impairment variously called attenuation distortion or frequency distortion.
In the stag (A) the skull is high, showing but little of that anterior attenuation which is such a distinctive feature of the skull of the elk (C).
The incorrect left-handed way, which even Steve Jobs has been known to use, apparently can cause "attenuation" of the phone's antenna performance, Apple spokesman Steve Dowling told me on Thursday.
And Motorola's Sanjay Jha told the paper that tests conducted by their engineers show that the iPhone 4 suffers from more serious 'attenuation' than its rivals.
