Size and contrast threshold for legibility
Summary | In one of the sensory characteristics database of elderly persons and persons with disabilities, it is a database that can estimate the legible font size of a letter and a digit by setting design parameters of the display character (font, characters, and luminance contrast between a character and background) and their conditions of use (user’s age and viewing distance). In addition, this database can estimate the legible luminance contrast between a character and background by setting design parameters of the display characters (font, characters, and size) and their conditions of use. |

Solid-State NMR Spectral Database
Summary | Solid-State NMR Spectral Database (SSNMR_SD) is a spectral database, which includes NMR spectra of mainly solid samples. Most of the spectra have been measured by solid-state NMR researchers in our institute, National Institute of Advanced Industrial Science and Technology (AIST), Japan (or the former Institutes, National Chemical Laboratory for Industry and National Institute of Materials and Chemical Research). |

Sound pressure level of auditory signals
Summary | In one of the sensory characteristics database of elderly persons and persons with disabilities, it is a database that provides a sound pressure level range of auditory signal that is audible and comfortably loud when heard in noise.The range is determined by taking the effects of age-related hearing loss.Based on the range, this application judges whether the level of auditory signal is suitable for use in the noise that is specified. |

Speech recognition scores related to hearing ability
Summary | In one of the sensory characteristics database of elderly persons and persons with disabilities, this database presents a relation between speech-to-noise ratio in decibels and the percentage correct of word recognition measured using high-familiarity word lists.Both test panels and test words were Japanese.The graph is displayed the sound pressure level difference between the noise and the sound as a parameter. |

Statistical distribution of hearing threshold levels as a function of age (ISO 7029)
Summary | In one of the sensory characteristics database of elderly persons and persons with disabilities, it is a database that presents statistics of the hearing-threshold-level distribution as a function of age.The values are displayed for men and women separately in the form of an audiogram.For retrieving data of Japanese people only, see Statistical distribution of hearing threshold levels as a function of age (Japanese data). |

Statistical distribution of hearing threshold levels as a function of age (Japanese data)
Summary | In one of the sensory characteristics database of elderly persons and persons with disabilities, this is the database that presents statistics of the hearing-threshold-level distribution of Japanese individuals as a function of age. The values are displayed for men and women separately in the form of an audiogram. For international data adopted in ISO 7029[1], see Statistical distribution of hearing threshold levels as a function of age (ISO 7029). |
