Effect of signal to noise ratio on the speech perception ability of older adults
Background: Speech perception ability depends on auditory and extra-auditory elements. The signal-to-noise ratio (SNR) is an extra-auditory element that has an effect on the ability to normally follow speech and maintain a conversation. Speech in noise perception difficulty is a common complaint of the elderly. In this study, the importance of SNR magnitude as an extra-auditory effect on speech...
متن کاملSignal-to-Noise Ratio Estimation
Of the many measures that characterize the performance of a communication receiver, signal-to-noise ratio (SNR) is perhaps the most fundamental in that many of the other measures directly depend on its knowledge for their evaluation. In the design of receivers for autonomous operation, it is desirable that the estimation of SNR take place with as little known information as possible regarding o...
متن کاملOptimising the signal-to-noise ratio
A long-term aim of current research into the frequency assignment problem is to identify features that would enable us to classify instances of the problem in terms of certain easily-computed parameters. Although there are good mathematical reasons why this may be impossible in full generality, experimental evidence is emerging which suggests that instances which occur in practice may be amenab...
متن کاملAchieving high signal-to-noise ratio in transient reflectivity measurements
Transient reflectivity measurements using ultrashort pulse pump-probe techniques can provide very useful information on fast carrier dynamics in semiconductors. Several non-trivial problems encountered in measuring reflectivity changes have been described. These changes can be very small (ΔR/R ~10 or less) and hence measuring these small changes is not straightforward. The possible solutions in...
متن کاملComment on "Signal-to-noise ratio gain in neuronal systems".
We discuss the gain in signal-to-noise ratio (SNR) recently reported by Liu et al. [Phys. Rev. E 63, 051912 (2001)] in the Hodgkin-Huxley neuronal model. We show first that the possibility of signal-to-noise ratio enhancements can be checked by consideration of the statistical characteristics of switching between the system states, and we examine how the SNR depends on the shape of a periodic s...
