For the section 'In Marine Mammals' Ican add additional information: Researchers customarily divide marine mammals into five hearing groups based on their range of best underwater hearing. (Ketten, 1998): Low-frequency baleen whales like blue whales (7 Hz to 35 kHz); Mid-frequency toothed whales like most dolphins and sperm whales (150 Hz to 160 kHz) ; High-frequency toothed whales like some dolphins and porpoises (275 Hz to 160 kHz); Seals (50 Hz to 86 kHz); Fur seals and sea lions (60 Hz to 39 kHz).

I can contribute the following text, which is modified and expanded from my page on testing the hearing of whales and dolphins. I'd like to get a little feedback before simply replacing the current text. I think the current text is problematic in several ways.
An audiogram is a graphical representation of how sensitive a subject is to acoustic stimuli across a range of frequencies. Frequency is placed on the X axis, usually with a logarithmic scale, and threshold values, usually in decibels, are plotted on the Y axis. For a behavioral audiogram, researchers obtain the needed threshold values by training subjects to respond to test tones with a specific behavior, which allows the tester to determine which tones have been heard and which were not heard (but see detection theory). For most humans, this may be accomplished by asking them to press a button or speak a word when they hear a test tone. From repeated trials, researchers estimate the threshold of hearing at each test frequency. Researchers do the same for a number of frequencies of test tones to find the audiogram of the subject.
For a behavioral audiogram, the subject is trained to make a response to an acoustic stimulus. The acoustic stimuli are given at many different frequencies and amplitudes, and an estimate is made of the threshold of hearing for each frequency. This approach contrasts with audiograms taken using electronics to pick up the faint signals of the brain's response to those stimuli, or neurophysiological audiograms. A common approach to obtain a neurophysiological audiogram is to monitor the auditory brainstem response (ABR). [2] While a neurophysiological audiogram by ABR has the advantage of not being dependent on having trained subjects, it has the disadvantage of requiring even more sophisticated equipment and impeccable technique in order to carry it off. Also, neurophysiological and behavioral audiograms do not usually agree precisely, even when taken on the same subject. A neurophysiological audiogram tends to indicate several decibels better sensitivity across the tested frequencies than does a behavioral audiogram.
A neurophysiological method for human subjects that is not as precise as ABR, but which can be accomplished with less complex equipment, relies upon otoacoustic emission. The healthy human ear not only transduces received sound energy, but also produces evoked otoacoustic emission of sound in response to acoustic stimuli. A small microphone placed in the external ear canal can pick up these small signals and indicate that the ear can react to a particular stimulus, or indicate a hearing deficit if no response occurs to a normally audible test tone. Such a technique is useful for constructing an audiogram of a human subject who cannot complete a behavioral audiogram, as in severe cases of autism.
As anthropogenic noise becomes more widespread, concerns about impacts of noise on animal populations grows. Audiograms for species become important tools for researchers and policy makers to take into account when dealing with anthropogenic noise. Unfortunately, relatively few species of birds or marine mammals have had audiograms constructed for them. For example, there is no audiogram of any type available for any mysticete cetacean. [3]
A problem with audiograms of non-human subjects is that there is often a tendency to use an audiogram obtained from a single subject and treat that as a representative audiogram for an entire species. This famously led to many years of confusion, from 1972 to 1999, as researchers believed that killer whales could not hear frequencies above about 32 kilohertz, based upon an audiogram of one subject. Later, audiograms taken on other killer whales revealed that their hearing was similar to that of other odontocete cetaceans, with ultrasound sensitivity up to about 120 kilohertz, indicating that the original subject had extensive high-frequency hearing loss. Szymanski et al. 1999
Another issue concerns the completeness of testing for an audiogram. For decades, shad were considered to have an ordinary audiogram for fish, with peak sensitivity under 1 kHz and an upper limit of hearing between 1 and 2 kHz. Further testing, however, demonstrated that shad actually could detect ultrasonic sound up to about 180 kHz. [4]

I know wikipedia is not the best source for "reliable" information (or at least, that is what is drilled into our minds every time we consider using it as a resource), but I am trying to discover information relating to the maximum hearing range of dogs (and to a lesser extent, humans). Unfortunatly, the image provided (the dark coloured bar graph(?) with numerous animals's hearing ranges) contradicts the text information, citing a maximum hearing range of 23kHz for humans (20kHz in the text, and most other resources) and 45kHz for Dogs (60kHz in the text, and little information given in other resources). Clarification on this information or links to more recent or non-conflicting sources would be appreciated. Thanks, Jonzay (AKA -- 203.214.151.1 ( talk) 12:50, 20 May 2008 (UTC))

I've done what I could to fix things up. The sources themselves are pretty inconsistent, unfortunately. (I've added a source that discusses these inconsistencies.) What seems to be clear is that (in general) cats can hear higher frequencies than dogs which can hear higher frequencies than humans - for lower frequencies, it's less clear. The references to ranges in octaves were terribly inconsistent and uninformative (and sometimes mathematically wrong) - I've removed them. Further editing (particularly based on a high quality source) would be welcome. Rxtreme ( talk) 17:21, 28 December 2016 (UTC)

Can someone clarify the section discussing the hearing range of mice. It first says that the low end is at 1KHz (which is quite a bit lower than the given human range listed above it) but almost immediately continues by saying that mice can not hear the lower frequencies that humans do. As I read it now, this looks like a contradiction. The only way that I can see how this would not be contradictory is (and this is quite a stretch of trying to force a non-contradictory situation) if mice were to have sensitivity to ranges below human hearing, but then lose sensitivity in the range of the lower human frequencies, but then the mice sensitivity picks back up. However, this would seem to me as very unlikely, and IF this were the case, this should be indicated with citation. At the moment, I would guess someone goofed up when they wrote the second statement. —Preceding unsigned comment added by 71.196.135.148 ( talk) 20:16, 26 November 2009 (UTC)

I'm one of the environmental judges at the Brussels Capital District. We have many cases on the impact of gsm's/mobile phones/wimax technologies and Natura 2000 sites. Anybody has any knowledge about nuisance between e.g. gsm etc. frequencies and pillars put in Natura 2000 sites - roads passing such sites - and e.g. interference with e.g. frequencies used by bats, in that bats would e.g. stay away from gsm pillars as these bats or other animals can't "see" there anymore?
I assume not as soundwaves are pressure waves and gsm waves are electromagnetic waves and I assume an EM wave doesn't cause a pressure wave, i.e. an audible wave. But can an EM wave make a little hearing hair vibrate and thus make it audible? Moreover, bats hear in the kHz range and mobile phones are in the MHz range.
"Bats ... hearing range varies by species; at the lowest it can be 1 kHz for some species and for other species the highest reaches up to 200 kHz. Bats that can detect 200 kHz cannot hear very well below 10 kHz.[8] In any case, the most sensitive range of bat hearing is narrower: about 15 kHz to 90 kHz."
From http://en.wikipedia.org/wiki/Insect#Sound_production_and_hearing :"Mosquitoes have been found to hear up to 2 MHz., and some grasshoppers can hear up to 50 MHz." Quote from GSM frequency bands: the ranges goes from 380.2 to 2.100 MHz.

The article clearly states that normal human hearing is given as 20 Hz to 20 kHz. There is an audiograph with a caption that implies it describes normal human hearing, but it is limited to representing a range of 125 Hz to around 10 kHz (if I read the scale right, with the edge dots disconnected as though irrelevant). This is inconsistent with the article and leads to confusion: is the graph/caption right that it is typical to have absolutely no hearing below 125 Hz or above c. 10 kHz? or is the body right that it is normal to be able to hear both higher and lower sounds? (This is, indeed, why I went around to check what exactly this graph was showing, because it certainly wasn't showing what it said it was showing.)
The article on audiograms states:
But it does not cite it either. Would you like to remove the equivalent comment there?
Perhaps the graph is misplaced here, and some other image, or none, would be better.

I think it's time to remove the statement that auditory temporal resolution in humans to be around 5 microseconds, which is in contrast to all previous scientific research in the field of human auditory perception. This claim and the conclusion "that digital sampling rates used in common consumer audio (such as CD) are insufficient for fully preserving transparency" is based only on two papers by Dr. Milind N. Kunchur published in peer-reviewed papers back in 2007 and 2008. As far as I can see, these controversial results have never been replicated by other researchers.
There are obviously at least two major flaws in these papers:
1. The JND for intensity levels is lower than the quoted 0.7 dB for high sound levels (69 dB SPL): http://www.hydrogenaud.io/forums/index.php?act=Search&CODE=show&searchid=a283d4a762bdc5d4952f159b5711fa3c&search_in=posts&result_type=posts&highlite=%2BZwicker
2. Using square wave signals in such tests in inappropriate due to the unavoidable intermodulation distortion taking place in both the power amplifier and the speaker.
The author reports that the "absence of anharmonic distortion was verified by spectrum analyzing the acoustic output of the loudspeaker using an ACO Pacific (ACO Pacific, Inc., Belmont, California) model 7016 measurement microphone and a 4012 preamplifier with a 40 dB gain stage"
This microphone model however exhibits a relatively high inherent noise level that may have mask the intermodulation products (its dynamic range is 35dBA - 164dBA).
