Ss listened to a dichotic tonal sequence consisting of the repetitive presentation of the C major scale with successive tones alternating from ear to ear. The scale was presented simultaneously in both ascending and descending form, such that when a component of the ascending scale was in one ear, a component of the descending scale was in the other, and vice versa. All Ss channeled this sequen...

The International Agency for Research on Cancer classifies radiofrequency (RF) electromagnetic emissions of cell phones as possibly carcinogenic to humans [1] and suggests the use of hands-free devices such as earphones to reduce direct exposure of the brain to such emissions. In this paper, we present the design of a mobile application that exploits persuasive principles to encourage the use o...

This paper presents an Electronic Travel Aid (ETA) for visually impaired and blind people. This device enables a blind user to quickly and safely walk through obstacle cluttered and unknown environments with a combination of eye glasses and waist belt. The foremost innovation of this device is its ability to actively guide the user around obstacles in pursuit of a given target direction. Using ...

Several investigators have suggested that between-subject variations in hearing aid benefit may be related to between-subject variations in auditory resolution. Evaluation of this relationship is complicated by the need to assess resolution at several frequencies and levels in hearing-impaired listeners who may not tolerate lengthy test procedures. This paper reports data from normal-hearing li...

The loss of vision restrained the visually impaired people from performing their daily task. This issue has impeded free-movement and turned them into dependent a person. People in this sector did not face technologies revamping situations. With advent computer vision, artificial intelligence, situation improved to great extent. propounded design is an implementation wearable device which capab...

An acoustic stimulus presented at the ear of an anesthetized cat evokes an electrical response from the auditory nerve of that animal. Our primary stimuli to date have been clicks produced by feeding rectangular pulses of duration 0. 1 msec into a PDR-10 earphone. These short stimuli evoke spike-like responses, which are detected by a fine wire electrode placed within the bullar cavity. Suitabl...

The sequential sound therapy is a treatment for tinnitus with white noise that has some own characteristics. We describe the methodology, as well as their differences and similarities with the Tinnitus Retraining Therapy. The sequential sound therapy has been carried out to seventeen patients assisted during the year 2002. 26 generators of sound were adapted, of them, 22 had incorporated an ear...

One of the recent diagnostic tests to assess the function of otolithic organs is through vestibular evoked myogenic potential (VEMP) testing. There are equivocal findings on effect of aging on ocular VEMP (oVEMP) parameters with reference to latencies. Hence this study was taken up to investigate the age related changes in oVEMP parameters. This present study considered 30 participants in each ...

Abstract − Non-audio signals have been recorded in the flash ROM memory of a portable MP3 player, in WAV format file, to examine the possibility of using these cheap and small instruments as general-purpose portable data loggers. A 1200-Hz FM carrier modulated by the non-audio signal has replaced the microphone signal, while using the REC operating mode of the MP3 player, which triggers the voi...

There are few systematic comparisons of Etymotic ER-3A insert earphones versus supra-aural earphones in auditory brainstem response (ABR) measurement. We compared ER-3A insert earphones and two types of supra-aural earphones (TDH-39P and TDH-49P) in a group of normal hearing adults. Acoustic analyses revealed spectral and temporal differences among earphones. Behavioral and ABR thresholds to cl...
