Music Intensity in the Ear Canal in Quiet and in Subway Noise Using Four Different Headphones
… a sound level meter. A total of 4 different headphones were used to present the music clip in two conditions (in quiet and in 80dBA of subway noise). The music was played at 4 different iPhone volume settings: 25%, 50%, 75% and 100% of the maximum volume. Measured intensities were then …

IceBreakware : designing wearable technologies for spatial awareness and social interactions
… are focused on screens, our ears are covered by headphones and our attention jumps between apps. As a result, many of us are actually finding it harder to have face to face interactions with others than ever before. We are getting worse at communicating with the people around us, in the present, …

Active noise reduction headphone measurement: Comparison of physical and psychophysical protocols and effects of microphone placement
… the United States, Active Noise Reduction (ANR) headphones cannot be tested and labeled as hearing protection devices (HPDs) due to inherent limitations with the existing psychophysical headphone testing standard, real-ear attenuation at threshold (REAT). This research focused on the use of a …

HearThere : infrastructure for ubiquitous augmented-reality audio
… typically presented to listeners via speakers or headphones. Speakers make it extremely difficult to control what sound reaches each ear, which is necessary for accurately spatializing sounds. Headphones make it trivial to send separate left and right channels, but discard the relationship between …

LOCALIZATION ABILITIES OF PERSONAL AUDIO DEVICE USERS
… these listening situations with three different headphones as well as in an open ear condition. On average, listeners increased the music levels by 28 dB in the traffic noise (with smaller increases with noise-reducing insert earphones) and had significantly more localization errors in traffic …

Simulating the effects of aging and hearing loss on the masking-level difference
When testing binaural hearing under headphones, the stimulus (signal and noise) delivered to the two ears can either be the same (diotic) or different (dichotic). Once any part of the stimulus is changed between the ears, the signal becomes easier to detect compared to the diotic condition. The …

Performance and test-retest reliability of the digits-in-noise test used in the sound field
… the test is completed with coupling to headphones/earphones. However, due to several limitations, such as the lack of availability or inability to utilise headphones/earphones, performing tests with earphones/headphones may not always be possible. Therefore, this study aimed to determine …

Acoustic chase : designing an interactive audio environment to stimulate human body movement
… body movements. The physical set-up consists of headphones with attached sensors to pick up the movements of the head. Mathematic models calculate the behavior of the sound, its virtual motion path relative to the person, and how it changes over time.

Head Mounted Microphone Arrays
… signal processing algorithms. Placing a set of headphones on a human provides several desirable features such as hearing protection, control over the acoustic environment (via headphone speakers), and a means of communication. The shortcoming of headphones is the complete occlusion of the pinnae …
