Voice prostheses are available in different types of architecture und from different producers. Especially the ones with antifungal properties are characterized by a high pricing. The aim of this paper is to check, whether these prices are reflected by the prosthesis life time.A Benchmarking with usage of mean lifetime and prosthesis costs. Comparing Provox 1, Provox 2, Provox Vega, Provox ActiValve, ESKA-Herrmann, Blom Singer Classic, Phonax, Blom Singer Advantage.The voice prosthesis Provox 1 offers the best price-lifetime-ratio (1.0). It's 6.7-times higher than the one of the Provox ActiValve (0.15). In addition, the classic prostheses Provox 2 (0.53), Blom Singer Classic (0.54) and ESKA-Herrmann (0.72) offer a good ratio compared to Provox 1, too.The mean lifetime of the voice prostheses do not reflect the pricing. The Provox 1 offers the best ratio and should be used as a reference in pricing the prostheses.
语音假体有不同的类型结构，来自不同的生产商。特别是具有抗真菌特性的那些，其特点是价格高昂。本文的目的是检验这些价格是否体现在假体的使用寿命上。通过使用平均使用寿命和假体成本进行基准测试。比较Provox 1、Provox 2、Provox Vega、Provox ActiValve、ESKA - Herrmann、Blom Singer Classic、Phonax、Blom Singer Advantage。语音假体Provox 1提供了最佳的性价比（1.0）。它比Provox ActiValve的性价比（0.15）高6.7倍。此外，经典假体Provox 2（0.53）、Blom Singer Classic（0.54）和ESKA - Herrmann（0.72）与Provox 1相比也具有良好的性价比。语音假体的平均使用寿命并不能反映其定价。Provox 1提供了最佳性价比，应作为假体定价的参考。
