Why is there is no audio data to support the research on my blog? The reason is because with voice recordings, every listener has a different opinion and reply regarding the overall sound, quality, environment and sound equipment used to collect the data. It is sometimes difficult to explain in words and have the reviewing audience agree on detailed sound changes as well. This issue is not only referring to internet sound delivery but also real life too.
For example, in the past on my ‘Japanese Blog,’ I had recorded the voice of a normal singer and the voice of a patient who has a vocal cord nodule, and saved them to WAV files. Then shared them, with my findings, and awaited for others to review and give feedback.
I could clearly identify the two different voices when played back on my PC using my own personal sound equipment. The equipment I used was an amplifier (brand name: Luxman) combined with headphones (brand name: Beyerdynamic).
The voice of the patient who has the vocal cord nodule displayed (1) A hoarse voice and irregularly leaking air (2)Impaired tone and resonance(3)Small wheezing noise accompanied with the voice.
However, when using the built-in speakers of a PC, I myself and most of the people reviewing the data could not identify the differences between the two voices.
In that case study, detailed sound could not clearly be identified using PC factory speakers.
As stated above, I found out through trial and testing it is too difficult to share investigated sound data and compare those sounds, due to the sound equipment and also the audience also observing/reviewing its sound equipment. With such inconsistencies playing a factor, I firmly decided never to share any more sound data on a blog or in real life. I truly believe if I posted audio data files or movie clips, unpredictable evaluations and criticism may follow. Please accept this and understand that I can only share my research findings and conclusions.
Note:Everybody has a different ear shape and size, and sometimes that size is slightly or extremely different from the right to left ear. These differences will directly affect how people perceive the sounds they hear.
