Truerta support12/17/2022 The frequency related information obtained with measurements almost perfectly matched distance measurements based on just listenting and measuring with a tape measure. At no time was anything but loudness considered. Large sound absorbers based on high density fiberglass about a half a foot deep were applied to the wall that seemed to be generating the strongest reflecations and therefore were causing standing waves. It was found that there was a regular pattern of dips and peaks whose most noticeable effects were in a broad region around 50 Hz. Some of the audience complained about how thin and lacking in energy the sound was, while others complained about heavy bass and thick boomy sound. Then appropriate sound absobers are fabricated or otherwise obtained, and mounted for the most effective results.įor example a large meeting room had very uneven bass response. ![]() The usual work flow is to identify the frequencies where the standing waves are the strongest with the software previously mentioned, and then survey the architecture of the room for the larger more highly reflective surfaces whose dimensions and spacing match up with the dips and peaks that have been measured. Peaks can also be tamed with equalization. Usually, the best solution is to use absorbers (either broadband or narrow band) to damp them. Most of the time, we will match or beat their price, and give you a credit.Humps and dips in rooms are generally due to standing waves that correlate with distances between the alrger and more reflective surfaces in the room. If you discover any competitor outselling us in a particular product, whenever you purchase in large quantity, please bring it to our attention. Why? Most of the time, shipping a 10 lb parcel does not cost 10ĭon't be shy. Essentially, you are paying 10 times on shipping. Some merchants offer FREE shipping, but when you buy quantity 10, you pay 10 times total. Unlike those wholesale to public membership clubs, we do not charge any membership fee. The philosophy to offer quality products with little mark up has created unmatched customer loyalty for some successful membership based stores.

If you want to do acoustic testing of loudspeakers in addition to the above you will need a calibrated microphone (True Audio recommends the Dayton Audio EMM-6), a microphone preamplifier or mixer, an audio power amplifier to drive the speaker under test, and cables to connect the line-out of the sound card to the input of the audio power amp. To set up your own audio test lab you will need a digital voltmeter to calibrate TrueRTA for your sound card and a collection of cables and adapters for connecting electronic gear to your sound card for testing. TrueRTA also includes a digital voltmeter that reads true rms voltage and dBu levels, and an audio spectrum analyzer.
