  • Recording audio with level triggers - Sound Level Meters

    Recording audio from a sound level meter measurement is sometimes necessary. Perhaps you need to listen to identify the source of a noise or for post-processing – or even to play back to a project stakeholder. If a measurement is short, it’s easy enough to record audio for an entire measurement and afterward crop the relevant parts. However, measuring for days, weeks or months, ...

  • 50th anniversary of world`s first sound level meter

    Sound Level Meter Celebrates 50th Anniversary 2010 is the year we celebrate the 50th anniversary of Type 2203, the mother of all sound level meters. It was the world’s first precision hand-held and transitorised sound level meter. Produced for 21 years, it sold a record number of 17300 units. With its upgrades Type 2204 (Impulse time constant) and 2209 (peak detector), it accounted for a ...

  • Noise, sound, decibels, hearing

    A decibel–a measure of sound. Like all short answers, this one leaves out a lot. When we hear a sound, its because our brain has received a nerve impulse from the nerve cells in the Inner Ear, which consist of a bone, called the Cochlea because it resembles a snail shell. These cells have long “hairs” that project into fluid inside the cochlea. There is a hole in the cochlea ...

  • D.I.Y. Studio Construction

    CHAPTER 1. Introduction Being an engineering company specialized in noise and vibration control we often come across applications in music studios. Noise transmission in studios can be airborne (transmitted via the air) but also structure borne (transmitted via the building elements). Due to the large wave lengths occurring from low frequency sounds ...

  • Uncertainties in Environmental Noise Assessments - ISO 1996 - Effects of Instrument Class and Residual Sound

    ISO/DIS 1996-2.2 (2005) “Acoustics — Description, assessment and measurement of environmental noise — Determination of environmental noise levels” contains guidelines on assessing the uncertainties of the determined sound pressure levels. This depends on the sound source, measurement time interval, weather conditions, distance from the source, measurement method and instrumentation. Guidelines on ...

  • Batch blenders make modern mortars in China

    With no internal moving parts, blenders minimize abrasive wear and simplify cleaning at two SureBlock plants. In 1997, US-based SureBlock entered a joint venture with China's Tianjin People's Building Material Products Factory to make concrete masonry units (CMUs). Commonly known as concrete blocks, CMUs come in many shapes, sizes, and colors. They are mainly used to erect structural walls, ...

  • Controlling scale deposits in the pulp & paper industry

    The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product.  As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water ...

  • A novel spectrometer design for process and handheld infrared spectral measurements

    Introduction Infrared spectroscopy offers many unique advantages for measurements within an industrial environment. Historically, the technique has been used for a broad range of applications from the composition of gas and liquid mixtures to the analysis of trace components for gas purity analysis. In cases where a well-defined method of analysis is involved, such as the measurement of ...

  • Roll-press briquetting helps Iowa lime producer retain previously wasted fines as valuable product case study

    Adding a new 550 tpd rotary kiln more than doubled lime production capacity at Linwood Mining and Minerals Corporation's Buffalo Plant, located near Davenport, IA...but it also raised the problem of what to do with a greatly increased output of fines. Realizing that landfilling its plant property with waste fines at rates of up to 100 tpd would not be a good long-term solution, the company not ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...


  • Successful Dunbar Field Life Extension

    The advent of high-power multiphase pumps is changing the world of oil production. In particular, they allow continued production from fields that are nearing the end of their useful lives. These revolutionary pumps have been in operation since autumn 1999 on the Dunbar platform, in the UK sector of the North Sea. Multiphase pumping (MPP) is essentially a means of adding energy to the ...

  • A new DIRAC measuring speech intelligibility

    History   Speech intelligibility relates to the sound intensity modulations in the talker’s voice, as described by Houtgast et al. [1]. This principle is used to determine speech intelligibility from the remaining modulation at a receiver position, using a modulated noise source at the talker position. The noise spectrum represents that of a human voice, and modulations at ...

  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...
