Introduction: Pouch noise is associated with discretion and the perception that people will notice the ostomate is wearing a pouch. Pouch noise can be a compromising factor in the necessity of discretion sought by those using ostomy appliances; affecting one’s quality of life. This study shows quantitative evidence that a newly developed pouch film provides the quietest pouch available.
Methodology: An independent accredited lab was contracted to conduct sound level tests on a newly developed pouch film and similar currently available pouch films. Ten pouches per product group were tested over one second intervals for three minutes. Analysis was performed on A-weighted data over the frequency range of audible sound.
Results/Discussion: The range of audible sound for the human ear is found between 20 Hertz and 20,000 Hertz. A Hertz is a unit of frequency, also known as pitch. In all configurations of pouch types tested, the newly developed film clearly demonstrates a considerable reduction in sound levels compared with similar currently available films, particularly of frequencies most sensitive to the human ear (1,000-5,000 Hertz). The newly developed quiet pouch film is demonstrated to be 7 dB to 9 dB quieter than the closest similar currently available pouch film at what experts agree is the peak of sensitivity (3500 Hertz) for the different pouch types.1,2
Conclusion: Providing a pouch that reduces noise, that is, the rustling or crinkling sound that pouches make, offers enhanced discretion. This, in turn, can positively affect dignity and quality of life; sought after necessities in an ostomy population.
