One significant concern that pilots have about cockpit auditory warnings is that the signals presently used lack a sense of priority. The relationship between auditory warning sound parameters and perceived urgency is, therefore, an important topic of enquiry in aviation psychology. The present investigation examined the relationship among subjective assessments of urgency, reaction time, and brainwave activity with three auditory warning signals. Subjects performed a tracking task involving automated and manual conditions, and were presented with auditory warnings having various levels of perceived and situational urgency. Subjective assessments revealed that subjects were able to rank warnings on an urgency scale, but rankings were altered after warnings were mapped to a situational urgency scale. Reaction times differed between automated and manual tracking task conditions, and physiological data showed attentional differences in response to perceived and situational warning urgency levels. This study shows that the use of physiological measures sensitive to attention and arousal, in conjunction with behavioural and subjective measures, may lead to the design of auditory warnings that produce a sense of urgency in an operator that matches the urgency of the situation.

Northwestern University researchers, led by Dr Nina Kraus, found that poor readers had reduced neural response (auditory brainstem activity) to rhythmic rather than random sounds compared to good readers. In fact the level of neural enhancement to acoustic regularities correlated with reading ability as well as musical aptitude. The musical ability test, specifically the rhythm aspect, was also related to reading ability. Similarly a good score on the auditory working memory related to better reading and to the rhythm aspect of musical ability. Dr Kraus explained, "Both musical ability and literacy correlated with enhanced electrical signals within the auditory brainstem. Structural equation modeling of the data revealed that music skill, together with how the nervous system responds to regularities in auditory input and auditory memory/attention accounts for about 40% of the difference in reading ability between children. These results add weight to the argument that music and reading are related via common neural and cognitive mechanisms and suggests a mechanism for the improvements in literacy seen with musical training."

Are you an auditory learner?

Researchers from King's College London Institute of Psychiatry, in collaboration with Bellvitge Biomedical Research Institute (IDIBELL) and the University of Barcelona, mapped the neural pathways involved in word learning among humans. They found that the arcuate fasciculus, a collection of nerve fibres connecting auditory regions at the temporal lobe with the motor area located at the frontal lobe in the left hemisphere of the brain, allows the 'sound' of a word to be connected to the regions responsible for its articulation. Differences in the development of these auditory-motor connections may explain differences in people's ability to learn words. Researchers used diffusion tensor imaging to image the structure of the brain before a word learning task and functional MRI, to detect the regions in the brain that were most active during the task. They found a strong relationship between the ability to remember words and the structure of arcuate fasciculus, which connects two brain areas: the territory of Wernicke, related to auditory language decoding, and Broca's area, which coordinates the movements associated with speech and the language processing. In participants able to learn words more successfully their arcuate fasciculus was more myelinated i.e. the nervous tissue facilitated faster conduction of the electrical signal. In addition the activity between the two regions was more co-ordinated in these participants. Dr Catani concludes, "Now we understand that this is how we learn new words, our concern is that children will have less vocabulary as much of their interaction is via screen, text and email rather than using their external prosthetic memory. This research reinforces the need for us to maintain the oral tradition of talking to our children."

This article talks about learning styles (audio, visual, kinesthetic) and how there has not yet been conclusive proof that they actually exist. It cites a Psychological Science journal, as well as psychologist Dan Willingham. However, while it states there has been no scientific evidence to prove the existence of learning styles, it does not actively disprove their existence.

Learning to play a musical instrument leads to changes in the brain's auditory system. The resulting auditory fitness may aid in other forms of communication, such as speech, reading, learning a foreign language, and understanding speech in a noisy environment.

wonderful radio interview with the woman who first discovered the songs of whales and is now researching how elephants communicate outside of human auditory range

"Mondegreen" means a misheard word or phrase that makes sense in your head, but is, in fact, entirely incorrect. Hearing is a two-step process. First, there is the auditory perception itself: the physics of sound waves making their way through your ear and into the auditory cortex of your brain. And then there is the meaning-making: the part where your brain takes the noise and imbues it with significance. That was a car alarm. That's a bird. Mondegreens occur when, somewhere between the sound and the meaning, communication breaks down. You hear the same acoustic information as everyone else, but your brain doesn't interpret it the same way.

This article is about how the auditory skills of hearing impaired children is affected by the amount of music and singing is in their live. A study conducted by a University in Helsinki measured different things connected to music and singing to brain responses in children with cochlear implants.

This article talks about an illusion our brain pulls on called the McGurk effect. This is when visual speech is mismatched with auditory speech and can result in the perception of an entirely different message. The example the article uses is if the visual "ga" were combined with the sound "ba", this results in the perception of "da." Vased on the principle of causal inference, researchers were able to create an algorithm model of multi-sensory speech perception. What this means is that when your brain is given a particular pair of auditory and visual syllables, it calculates the likelihood that they are from a single talker compared to multiple talkers and uses this likelihood to determine the final speech perception.

This Scientific American blog article provides a handy run-down of research findings re: music's effect on the brain, including 1. Musicians are better able to process foreign languages because of their ability to hear differences in pitch, and have incredible abilities to detect speech in noise. Even those w/ a few years of music training showed more robust neural processing of sounds. Music "tones auditory fitness", critical for perceiving speech and distinguishing, recognizing and processing conversation in noisy environments. 2. Musical training and education may confer linguistic, mathematical, and spatial benefits, and promote social development/"team player" capacities.

Brain-imaging studies have shown that music activates many diverse parts of the brain, including an overlap in where the brain processes music and language. Brains of people exposed to even casual musical training have an enhanced ability to generate the brain wave patterns associated with specific sounds, be they musical or spoken, said study leader Nina Kraus, director of the Auditory Neuroscience Laboratory at Northwestern University in Illinois. Musicians have subconsciously trained their brains to better recognize selective sound patterns, even as background noise goes up. In contrast, people with certain developmental disorders, such as dyslexia, have a harder time hearing sounds amid the din. Musical experience could therefore be a key therapy for children with dyslexia and similar language-related disorders. Harvard Medical School neuroscientist Gottfried Schlaug has found that stroke patients who have lost the ability to speak can be trained to say hundreds of phrases by singing them first. Schlaug demonstrated the results of intensive musical therapy on patients with lesions on the left sides of their brains, those areas most associated with language. Before the therapy, these stroke patients responded to questions with largely incoherent sounds and phrases. But after just a few minutes with therapists, who asked them to sing phrases and tap their hands to the rhythm, the patients could sing "Happy Birthday," recite their addresses, and communicate if they were thirsty. "The underdeveloped systems on the right side of the brain that respond to music became enhanced and changed structures," Schlaug said at the press briefing.

Individuals who are born deaf use the "hearing" part of their brain to feel touch and to see objects, suggests new research that highlights the plasticity of the human brain. The new study, detailed online July 11 in The Journal of Neuroscience, shows that deaf people use the so-called auditory cortex to process both touch and visual stimuli much more than hearing individuals do.

"Our main conclusion is that delays in word onset facilitate word recognition, and that such facilitation is independent of the type of delay. ... Our findings support the perhaps counterintuitive conclusion that fillers like um can sometimes help (rather than hinder) listeners to identify spoken words. But critically, the data show that the same is true for silent pauses and pauses filled with artificially generated tones. "

Great article that explains different learning styles

The brains of people who cannot hear adapt to process vision-based language, in addition to brain changes associated with the loss of auditory input.

Noise pollution can cause health effects while reading.

A study conducted by neuroscientists from Northwestern University showed that the adolescent brain still has a considerable amount of neuroplasticity. The study also verified that music students developed improvements in auditory processing, which is crucial for verbal processing.

When driving, don't talk to your car - or your phone. That's the underlying message of new neuroscience published Thursday that raises new questions about the safety of voice-activated technology in many new cars. The technology, heralded by many automakers, allows consumers to interact with their phones and their cars by issuing voice commands, rather than pushing buttons on the dashboard or phone. However, research found that the most complicated voice-activated systems, and the vocal and auditory tasks associated with them, can take a motorist's mind off the road for as long as 27 seconds after he or she stops interacting with the system. Even less complex systems can leave the driver distracted for 15 seconds after a motorist disengages. See the article for an embedded .pdf of the full study. But good news: apparently listening to the radio or audiobooks don't pose much distraction.
