"Increase sound" is not a valid grammatical sentence in English, but it can be used as an imperative (command) in certain contexts.
For example, "Please increase sound to hear the instructions."
The results of this research indicate that the combination of steel and textile fibers contaminated with rubber powder increase sound absorption when compared to ordinary or rubberized concrete.
In room acoustics design, one-dimensional periodic surfaces, such as ribbed or corrugated walls, are ordinary used to scatter reflected sound and to increase sound field diffuseness.
As a consequence, high VF of FCR (80 100%) can be incorporated to concrete for non-structural uses to increase sound absorption.
Methods to increase sound level, fidelity and quality produced from vibrating lamina such as piezoelectric actuators, vibrating plates or vibrating films are presented.
This operating regime at low Strouhal numbers enables to increase sound absorption at low frequencies over a larger frequency bandwidth around the peak absorption frequency than the one obtained with a damping system working at high Strouhal numbers.
The test results indicate that shunted PZTs can increase sound transmission loss by approximately 6 dB for a pure tone input at 162 Hz, and 7 dB for a broad band input of 10 10000 Hz.
And though a 25% salary increase sounds generous, a standard state salary is still only $120 a month, and the unemployment rate is among the region's highest.
"If we need to sit down and have more meetings and outreach, we will do that too". "I understand that a 109% increase sounds horrible to people," he added.
A larger ratio suggested increased sound in the apical areas and a smaller ratio increased sound in the diaphragmatic areas.
Recent changes in restaurant design have also increased sound levels.
The degradation efficiency of formaldehyde increased with increasing sound frequency ranging from 50 to 100 Hz, further decreased with increasing sound frequency from 100too 150 Hz.
