An omnidirectional source is required in many acoustic measurements. Commonly a dodecahedron speaker is used but due to various factors (e.g., high cost, transportation difficulties) other acoustic sources are sometimes preferred. In this review, fifteen acoustic source alternatives to a dodecahedron speaker are presented while emphasis is placed on features such as omnidirectionality, repeatability, adequate sound pressure levels, even frequency response, accuracy in measurement of acoustic…

Study and Improvement of Acoustic Conditions in Public Spaces of Shopping Malls

A method for qualitative assessment of the public space acoustics is proposed and average absorption coefficients are found by means of the Sabine’s equation and can be used for quick estimation of the reverberation time in similar spaces without the absorbing treatment.

Experimental study of impulse sound transmission between rooms

This paper presents experimental results of a study of the sound transmission between two rooms in one of which an intensive short impulse is radiated. The room with the source is treated by a sound

Sensitive Parameters of Dynamic Excitation on Fuze Airflow-Induced Acoustic Generator

The orthogonal experiment method is used to study the sensitive parameters that control fluid dynamic sound sources, and the results show that the annulus, the confronting distance, and cavity length can all have an impact on the sound pressure amplitude.



Impulse source versus dodecahedral loudspeaker for measuring parameters derived from the impulse response in room acoustics.

It is found that using impulse sources leads to greater variation in the results, especially at low frequencies, and a new descriptor for dodecahedral sources reflecting the influence their lack of omnidirectionality produces on measuring acoustic parameters is proposed.

Low Cost Omnidirectional Sound Source Utilizing a Common Directional Loudspeaker for Impulse Response Measurements

Alternative low-cost sources (e.g., balloons, gun fires) are used for impulse response measurements when a dodecahedron speaker is not available. This study sets to explore the applicability of a

Results show that averages of three measurements carried out at 30° angular steps are closer to actual values and show much less fluctuation, and an averaging of the directional intensity components of the selected responses stabilizes the spatial distribution of the reflections.

The Source Directivity of a Dodecahedron Sound Source determined by Stepwise Rotation

An omnidirectional sound source is commonly used in room acoustical measurements. The omnidirectional directivity is usually approached by placing 12 loudspeakers in a regular 12-face polyhedron,

Realization of an omnidirectional source of sound using parametric loudspeakers.

The omnidirectional parametric loudspeaker (OPL), consisting of a sphere with hundreds of ultrasonic transducers placed on it, has been constructed and has performed better than the conventional loudspeaker especially for frequencies higher than 500 Hz, its main drawback being the difficulty to generate intense pressure levels at low frequencies.

Evaluation of a three-way omnidirectional sound source for room impulse response measurements

Commercially available omnidirectional loudspeakers, which are used to measure room impulse responses, typically have a limited bandwidth and are only omnidirectional below approximately 1kHz. To
