psychoacoustics

While planning my surround sound setup I got stuck at the questions if I want to get add a center channel or not. For movies and native surround music like Dolby Atmos music a center channel makes absolutely sense because there is native content mixed to that channel. But most of my music still...

My home audio chain is mostly digital and looks like: [PC] -> [USB to SPDIF] -> [digital equalizer] -> [digital crossover + DACs] -> [power amps] -> [subs and mains] I recently bought the Topping D10B for USB to SPDIF conversion, and that offered a possibility to apply the Behringer SX3040 V2...

It started with the fact that I was disappointed with the AKG K361 headphones, they seem to fit the Harman curve, plus I used the oratory1990 EQ, started listening and ... I didn’t like it. I think: well, how is it, here are the headphones, smartly made for the right purpose, they have much...

ASR reviews for DACs often capture "beyond hearing threshold'. We each are susceptible to psychoacoustics. For amps, we select from measurements, power and use features. For DACs in the 'Blue' zone of highly rated, why would we select one that has the higher cost, assuming features not...

Hello everyone! Today I am asking for your help in a research study for a class on research methods. Participation will not require anything from you except some time and a computer with web browsing and audio playback capabilities. Permission to post this here has been provided by Amir, for...

I bought I extra copy for a reason that fell through long ago. This is a brand new hard copy of Mr. Toole's opus book Sound Reproduction: The Acoustics and Psychoacoustics of Loudspeakers and Rooms,3rd Edition I have been on this forum awhile, hopefully you can trust me with the sale of an...

Hi, I wanted to know you opinion on cutting frequencies below 20 Hz, I saw a lot of speakers that have small woofer that doesn't extend well past 50-60Hz, but that's not the case with headphones, with many reviews recommending equalization of bass to Harman target and even with linear bass...

I had a hearing test yesterday. It's been 4 years since my last one and with constant tinnitus caused by concerts, motorcycles etc I should do them regularly. The verdict that my hearing was fine apart from age related loss. Probably exacerbated though. My hearing in fine in the critical...

According to Stig Carlsson’s philosophy of the speaker and room as a system. http://user.faktiskt.io/schmutziger/OA51 FAQ/pdf/carlsson_ortho_design_principles.pdf Let’s push for a resurgence of a systems level approach for speaker design and not just plop down a couple of mundane boxes on the...

Er, actually, this thread should probably be in the psychoacoustics area. Can a mod move it? Introduction and observation: Following the fairly well received post on the relationship between group delay and spatial effects in headphones, I thought I'd start a new thread on the matter, gathering...

Double blind wine tasting (and the impact of the bottle)? Coke vs Pepsi and functional MRIs? Very interesting topics to read about that highlight the complexities of human perceptions and all the factors that influence it. I have read a lot of behavioral economics and psychology books...

Roughly sorted according to theme, and chosen because I think they're worth listening to. The difficulty ranges from introductory to real heavy. Part of the way I dive into a topic is to find lectures by knowledgeable people and then build archives. So maybe others will find this useful as...

In my attempt to find my preferable FR for headphones, I went on various sites to explore and found that RTINGs had a decent way of documenting them. I know that since they might have had only one unit at hand, their charts might not be representative of an aggregated FR curve for their devices...

Thought I'd start a new thread about this. For quite some time I've been intrigued by blind testing, and whether that's the end all be all when it comes to audible differences in audio (or preferences). A couple of years ago, when I was still struggling in the passive quagmire, this led me to...

This is an article I wrote for Widescreen Review Magazine which came out a couple of years ago. This is a revised and updated version. ---- Audibility of Small Distortions By Amir Majidimehr Spend five minutes in any audio forum and you immediately run into food fights over audibility of small...

This is a topic that I expect some of the members in the forum who are in the medical field to also know. If so, feel free to contribute :). The outer ear is designed to collect and magnify the mid-range frequencies. This is the reason the equal loudness graphs of Fletcher Munson show much...
