  1. Social impacts of tourism as perceived by state–planned tourism destination residents: the case of Huatulco, Mexico

    International Journal of Tourism Anthropology 2(1):34 (2012)

    Drawing from primarily quantitative data collected in 2010 among adult residents (n = 204) in the state–planned tourism destination of Huatulco, Oaxaca, Mexico, this paper examines the ways in which local residents perceive the social effects of regional tourism development. Currently, socio–demo...
  2. [Non-auditory effects of noise].

    Giornale italiano di medicina del lavoro ed erg... 33(3):345 (2011) PMID 22073688

    Non-auditory effects of noise involve several systems and functions, the most important of which are the cardiovascular, the vestibular and the psychic. Although several studies correlated noise exposure to some pathologies, like hypertension and anxiety disorders, and recent analysi...
  3. Companding to improve cochlear-implant speech recognition in speech-shaped noise.

    Journal of the Acoustical Society of America 122(2):1079 (2007) PMID 17672655

    Nonlinear sensory and neural processing mechanisms have been exploited to enhance spectral contrast for improvement of speech understanding in noise. The "companding" algorithm employs both two-tone suppression and adaptive gain mechanisms to achieve spectral enhancement. This study implemented a 50...
  4. The effects of speech presentation level on acceptance of noise in listeners with normal and impaired hearing.

    Journal of Speech, Language, and Hearing Research 50(4):878 (2007) PMID 17675593

    The effects of speech presentation level on acceptance of noise were evaluated using global ANLs and ANL growth. Results showed global ANL and ANL growth were not significantly different for listeners with normal and impaired hearing, and neither ANL measure was related to pure-tone average for list...
  5. Effects of artifact rejection and bayesian weighting on the auditory brainstem response during quiet and active behavioral conditions.

    American Journal of Audiology 15(2):154 (2006) PMID 17182880

    ABRs recorded during the quiet behavioral condition resulted in minimal differences in wave V amplitude and noise reduction improvement, suggesting that the 2 techniques were equally effective under ideal recording situations. During the active behavioral condition, however, the techniques differed...
  6. Designing better physical environments for today's nurses.

    The South Carolina nurse / South Carolina Nurse... 13(4):22 (2006) PMID 17165649

  7. Influences of leaf shapes on performance of progressive multi-leaf springs

    International Journal of Vehicle Design 34(1):65 (2004)

    Influences of the shapes of spring leaves in a progressive multi-leaf spring were investigated using the semi-analytic model based on the Euler beam theory and the FEM model using ABAQUS. The trends in shifting of the locations of the contact point are found to change with the shapes of spring leaves...
  8. Time-delay estimation of reverberated speech exploiting harmonic structure.

    Journal of the Acoustical Society of America 105(5):2914 (1999) PMID 10335640

    The relative time delay associated with a speech signal received at a pair of spatially separated microphones is a key component in talker localization and microphone array beamforming procedures. The traditional method for estimating this parameter utilizes the generalized cross correlation (GCC),...
  9. Maturation of medial efferent system function in humans.

    Journal of the Acoustical Society of America 105(4):2392 (1999) PMID 10212420

    Otoacoustic emissions are typically reduced in amplitude when broadband noise is presented to the contralateral ear. This contralateral suppression is attributed to activation of the medial olivocochlear system, which has an inhibitory effect on outer hair-cell activity. By studying the effects of c...
  10. Perception of microphone noise in hearing instruments.

    Journal of the Acoustical Society of America 104(6):3364 (1998) PMID 9857504

    In a well-designed instrument the noise level is reduced until it is dominated by the front end noise. In a hearing instrument this is the microphone noise. This paper examines the perception of noise in a hearing instrument by both normal-hearing and hearing-impaired listeners. The noise levels are...
