Webb16 feb. 2024 · The speech detection threshold can be used as a cross-check of the air conduction audiometry and should closely agree with the PTA (Pure Tone Average). The PTA can be calculated in different ways but is usually the average of thresholds obtained at 500, 1000, and 2000 Hz. It is generally accepted that if the PTA and the SRT is within ± 6 … Webbexample, irrespective of the packet reception ratios of the links, if the average of the link pairs is very high (close to 1.0), then us-ing a protocol that does not code works better than using a network coding protocol. Measuring on several 802.15.4 and 802.11 testbeds, we find that it varies significantly across network topologies and link ...
