  • This study suggests story telling-based scenery color plan that uses local story resource in order to raise possibility of success in making characterized town implemented by Ulju-gun, Ulsan Metropolitan City. Characterized town making project of Eoeumhari Town is the first in Ulsan, and detailed project planning is going underway to transform it into story telling street by providing local story to the resource of Eoeumhari Town. Ulju-gun expects big help in luring tourists and activating local economy by maintaining these towns. As in this way, local marketing that uses story telling is recently being taken as a desirable way of overcoming the limit of local development, and it suggest new possibility of scenery color plan. Therefore, I attempted to extract Brand Story from story resources based on climatic color of Eoeumhari Town and apply them to the color plan in order to unique color identity with a town as a unit. It is significant to study as it suggests a direction to discover values of color which can be used for establishing local identity and activating local community breaking from current color plan by large-scale maintenance implemented by each local government.

  • In most of hearing aids, amplification algorithms are used to compensate hearing loss, noise and feedback reduction algorithms are used and to increase the perception of speeches contrast enhancement algorithms are used. However, acoustic masking effect is occurred between formants if contrast is enhanced excessively. To confirm the masking effect in speeches, the experiment are composed of 6 tests; test pure tone test, speech reception test, word recognition test, pure tone masking test, formant pure tone masking test and speech masking test, and for objective evaluation, LLR is introduced. As a result of normal hearing subjects and hearing impaired subjects, more making is occurred in hearing impaired subjects than normal hearing subjects when using pure tone, and in the speech masking test, speech reception is also lower in hearing impaired subjects than in normal hearing subjects. This means that acoustic masking effect rather than distortion influences speech perception. So it is required to check the characteristics of masking effect before wearing a hearing aid and to apply this characteristics to fitting curve.

  • Although it is well-known that environmental noise can lead to hearing loss in individuals, the true extent of subway noise effects in the general population remains poorly understood. The purpose of the present study is to see changes of acoustic reflex thresholds and speech perception scores when passengers listen to music presented from their personal listening device in the subway. Forty subjects with normal hearing participated being divided into two groups, experimental and control groups. As a baseline, all subjects were measured by acoustic reflex thresholds in five test frequencies and Korean speech perception in noise (KSPIN) test at 0 and -5 dB SNR. In the experiment, the control group read newspaper or magazine in the subway noise, whereas the experimental group listened to music presented from their smartphone under the subway noise through speakers at 73.45 dBA for 60 min. After completing the experiment, two groups also conducted both acoustic reflex thresholds and KSPIN tests in the same condition as the baseline. The results showed that there was a significant difference of correct percent in speech-in-noise test between experimental and control groups and of that between two signal-to-noise ratios, which means the double noise exposure of 60 min might cause some degradation of speech perception when noise increases compared to only subway noise condition that was not statistically significant difference. We concluded that a risk of some degraded speech perception ability would be expected when passengers have a habit of listening to music in the subway noisy situation for a long duration.
