Sound Transmission Loss
Because of the large sound transmission loss in seawater, including geometric spreading and sound absorption, the sound intensity is rapidly attenuated with increasing propagating distances r. The input SNR (signal-noise ratio) for a specific receiver will correspondingly be lowered, or transmitting information cannot normally be detected.
Sound Transmission Loss - Siemens
Sound transmission loss is a function of frequency. The transmission loss performance of a certain material will differ greatly with frequency (see Figure 2, below). The y-axis of a plot represents how many dB the acoustic absorber reduces the incident energy. Figure 2: Sound transmission loss as a function of frequency.
Hearing loss could be among the long-term effects of coronavirus
Hearing loss could be the latest impact of coronavirus, as a study finds issues in patients up to eight weeks after they were discharged from hospital. More than 13 per cent of people who
Comparison of Music Sound Quality Between Hearing Aids
The purpose of this study was to examine the sound quality of hearing aid processed music across a wide range of hearing aid models and music genres. Specifically, we compared hearing impaired listeners’ subjective sound quality ratings of music processed by several premier hearing aids’ respective universal and music programs. Methods
Evaluation of Impairment Caused by MPEG Video Frame Loss
This article presents a study on the impact of video frame losses on the quality perceived by users. Video compression standards, such as MPEG, use a sequence of frames called Group of Pictures (GOP), which is a video compression method which a frame is expressed in terms of one or more neighboring frames.
Glossary - Industry Leading Sound Masking From Biamp
Sound Transmission Class (STC): an index of sound loss through a particular material as measured in a standardized acoustics lab test. It is derived from the amount of sound that is lost in sixteen standard 1/3 octave band frequencies from 125 Hz to 4000 Hz when transmitted through the material.
Home Insulation| Insulating for Sound | Noise, Health
An easy and economical method for increasing the sound transmission loss of a wall is to install sound absorbing acoustic insulation in the wall cavity. Installing fiberglass or mineral wool insulation batts between rooms such as bedrooms and adjoining bathrooms, or between a recreation room and a den or study will keep the noise level between
DAB vs DAB+ Radio Broadcasting: a Subjective Comparative Study
In the age of digital media, delivering high quality content to consumers is one of the most demanding tasks. There exist numerous broadcasting standards, with different pros and cons, and the DAB/DAB+ (Digital Audio Broadcasting) system is one of the most popular among them. From an engineer’s perspective, efficient resource management under limited bandwidth conditions has always been a
