Threshold of hearing by bone conduction. A contribution to international standardization.Threshold measurements with a Prcitronic KH 70 bone vibrator were carried out on 25 young, otologically normal subjects (50 ears) in the frequency range between 125 Hz and 8 000 Hz. The vibrator was applied ...
For a frequency of 1 kHz, the threshold of hearing is ___. The Threshold for Hearing: The unit used for detecting and measuring pure tones is called PHON. The sound is the form of energy that produces the sensation of hearing in our ears and the audible range in terms of frequency...
Threshold of hearing for random noise. The bonding in the molecule ion VO(H2O)(5)(2+) is described in terms of molecular orbitals. In particular, the most significant feature of the electronic s... R Hinchcliffe - 《Journal of Speech & Hearing Research》 被引量: 1发表: 1961年 ...
Absolute threshold refers to the smallest level of energy required for a stimulus to be detectable by the human senses (vision, hearing, taste, smell, and touch). Specifically, the degree of intensity should be detected 50% of the time. Any stimulus detected above the threshold is considered ...
In hearing, is place theory more correct than frequency theory? Explain your answer. What is stimulus threshold? What is the difference between stimulus intensity and stimulus frequency? How does distance relate to the spatial frequencies with one's perception? What are the two main ty...

A decreased speech understanding, an increased pure tone audiometry (PTA) threshold, an abnormal acoustic reflex threshold, and an abnormal auditory brainstem response (ABR) are some of the common findings of MS with symptoms of hearing problems [4]. Auditory Evoked Potential Inconsistency in Sudden...
the intensity at which speech is recognized as meaningful symbols; in speech audiometry, it is the decibel level at which 50% of spondee words can be repeated correctly by the subject. Farlex Partner Medical Dictionary © Farlex 2012
Objectives: Nearly half a century ago, administration of glycerol was shown to temporarily improve the threshold of hearing in patients with suspected Meniere's disease (glycerol test). Although a positive test result provides strong evidence of Meniere's disease, the test has not gained widespread...
2012). The ear is most sensitive to sounds that cover the speech frequencies (250 to 8000 Hz). There are several types of tests that audiologists use in assessing hearing. Pure tone audiometry presents pure (one-frequency) tones to each ear and determines the threshold of hearing for that...
